Extractions: Hans G. Dehmelt Hans G. Dehmelt says he "felt like dancing" when he heard that he'd won the Nobel Prize in physics in 1989. But the German-born American citizen was not surprised: "I'd been expecting it, because there were rumors that I was being considered." Dehmelt was honored for trapping a single electron as well as for isolating a single atom and watching it make quantum leaps. Due to Dehmelt's discovery, physicists had to revise their estimate of the size of an electron by a factor of 10,000. Accepting the prize was "wonderful," he says. "The physicists walked first into the Great Hall in Stockholm's Town Hall, as decreed by Nobel himself, and as befits the position of physics as the queen of the sciences." Then came chemistry, then physiology or medicine, then economics, then literature. (The Nobel Peace Prize is awarded in Oslo.) Since winning the prize, Dehmelt says ebulliently, "My life is now a bed of roses, an absolute bed of roses." He married his second wife after receiving the prize, but he had known her beforehand. Dehmelt is still active in his laboratory, and his research interests haven't changed their direction: "At my age, one is happy to stick to the tack one has chosen earlier," he says. "But the longer you follow the same tack, the more difficult it gets, and the smaller the return. Still, not many other people study single electrons."

Extractions: German-born American physicist who shared one-half of the Nobel Prize for Physics in 1989 with the German physicist Wolfgang Paul. (The other half of the prize was awarded to the American physicist Norman F. Ramsey.) Dehmelt received his share of the prize for his development of the Penning trap, an electromagnetic device that can hold small numbers of ions (electrically charged atoms) and electrons for periods of time long enough to allow their properties to be studied with unprecedented accuracy. Dehmelt served in the German army from 1940 until he was captured by U.S. forces in 1945. Having studied physics during the war under an army technical program, he resumed his studies thereafter at the University of Gottingen, graduating with a doctoral degree in physics in 1950. He went to the United States in 1952 and began teaching at the University of Washington in 1955. He became a full professor there in 1961, the year in which he also became a U.S. citizen. Dehmelt's Penning trap, which he developed in 1955, can confine electrons and ions in a small space for long periods of time in relative isolation. In 1973 Dehmelt used his device to isolate a single electron for observation, an unprecedented feat that opened the way for the precise measurement of key properties of electrons. Dehmelt and his colleagues went on to develop methods for measuring atomic frequencies and individual quantum jumps (the transitions between atomic energy levels) with unprecedented precision. In the 1970s Dehmelt used his trap to measure an electron's magnetic moment to an accuracy of four parts in a trillion, the most precise measurement of that quantity at the time.

Extractions: At Duke I had the pleasure of making the acquaintance of James Frank, Fritz London, Lothar Nordheim and Hertha Sponer. I advised Hugh Robinson, a graduate student of Gordy's in an NQR experiment, did my own research and also contributed some NMR expertise to an experiment by Bill Fairbank and Gordy on spin statistics in He/ lignment of the atom should show up in its optical absorption cross section, and (b), electron impact should produce aligned excited atoms. I put these two ideas to good use in 1956 in Seattle in an experiment entitled "Paramagnetic Resonance Reorientation of Atoms and Ions Aligned by Electron Impact." In this paper I first pointed out the usefulness of ion trapping for high resolution spectroscopy by Optical Pumping Techniques" of my first graduate student, Earl Ensberg, also made use of these novel optical pumping schemes and was finished in 1962. These early results were improved orders of magnitude by my doctoral student Philip Ekstrom in his 1971 thesis "Search for Differential Linear Stark Shift in Cs and Rb Using Atomic Light Modulation Oscillators."

Extractions: Penning trap. The University of Washington is a leading center for pioneering atomic and molecular physics techniques of high precision and using them for studying elementary particle forces and symmetries. The magnetic properties of the electron can be measured to 10 and compared to the predictions of Quantum Electrodynamics (QED). Forces within atoms that violate parity conservation or time-reversal symmetry can be revealed in sensitive atomic experiments. These experiments work on the frontier of modern technology, with the techniques involved having many applications. Mono-Ion Spectroscopy This research, for which Professor Hans Dehmelt was awarded the 1989 Nobel prize, makes use of the electromagnetic trap he developed to capture a single ion in a near-perfect vacuum. Spectra showing no other broadening than the natural line width have been obtained, and the observation of optical transitions in the 10 Hz range no wider than 1 millihertz are conceivable and being pursued. Departmental researchers have demonstrated the use of a single ion as a million fold amplifier.

Extractions: Dehmelt, Hans G. My father, Georg, had studied law at the Universitat Berlin for some years, and in the first World War had been an artillery officer. He was of a philosophical bend of mind and a man of independent opinions. In the depth of the depression he just managed to make a living in real estate. When the family fortunes had shrunk to ownership of a heavily mortgaged apartment building located in an overwhelmingly Communist part of Berlin, it seemed reasonable to move into one of the apartments ourselves as nobody paid any rent. Cannons were deployed on the streets on occasion and the class war had entered the class rooms. After a few bloody noses administered by a burly repeater, I shifted my interests from roaming the streets more towards playing with rudimentary radio receivers and noisy and smelly experiments in my mother's kitchen. In the spring of 1933 my mother, a very energetic lady, saw to it that, at the age of ten, I entered the Gymnasium zum Grauen Kloster, the oldest Latin school in Berlin, which counted Bismarck amongst its Alumni. This involved a stiff entrance examination and I was admitted on a scholarship. My father at that time expressed the opinion that I probably would be happier as a plumber. However, he apparently didn't quite believe this himself. < v Laser Fluorescence Spectroscopy on Tl+ Mono-Ion Oscillator." Unfortunately, this proposal infuriated one of the agencies funding our research to the degree that they terminated their support almost immediately. I was rescued by a prize from the Humboldt Foundation and an invitation by Gisbert zu Putlitz to initiate the proposed laser spectroscopy project in his Institute at the Universit?t Heidelberg. As the fruit of these efforts a paper "Localized visible Ba+ mono-ion oscillator" by Neuhauser, Hohenstatt, Toschek and myself appeared in 1980.

Extractions: Né à Görlitz (Allemagne), Dehmelt obtient son doctorat en 1950 à l'université de Göttingen. Il travaille plusieurs années comme chercheur à l'institut Hans Kopfermann de Göttingen. En 1952, il part aux États-Unis et mène des recherches à l'université Duke. En 1955, il entre à la faculté de l'université de Washington où il poursuit ses recherches et continue à enseigner. À partir des travaux de Wolfgang Pauli , Dehmelt tente, à l'aide d'un champ électrique tridimensionnel (le piège de Paul), de confiner des ions en suspension dans un espace réduit. En 1973, en appliquant à ce dispositif un champ magnétique puissant, il parvient à isoler et à conserver un seul électron. Il utilise ce système, appelé piège de Penning, pour étudier les propriétés magnétiques et les états de spin des électrons. Dehmelt met aussi au point une technique permettant de refroidir les particules étudiées de manière à ralentir leur mouvement et donc à accroître la précision des mesures faites. Dehmelt perfectionne ensuite ses techniques d'étude de particules atomiques et augmente la précision des mesures magnétiques relatives aux électrons. En 1980, il parvient à isoler, à refroidir et à photographier un seul ion dans le piège de Penning. En 1989, il a reçu le prix Nobel de physique avec le physicien allemand
