Extractions: Hofstadter, Robert US nuclear physicist who made pioneering studies of nuclear structure and the elementary nuclear constituents, the proton and the neutron. He established that the proton and neutron were not pointlike, but had a definite volume and shape. He shared the 1961 Nobel Prize for Physics. Hofstadter was born in New York and educated at City College and Princeton. From 1950 he was at Stanford, where his early work involved bouncing, or scattering, electrons from complex nuclei, such as gold. This produced accurate pictures of the charge distribution within nuclei. Gradually, smaller nuclei were studied by Hofstadter and his team, using electrons of increasing energy. By 1960, accurate data had been obtained for the proton and neutron, revealing the spatial distribution of charge and magnetization within these particles.

Extractions: Hofstadter, Robert (1915-1990), físico estadounidense premiado con el Nobel. Nacido en Nueva York, recibió el título de doctor en filosofía por la Universidad de Princeton en 1938, y se incorporó a la Universidad de Stanford en 1950. Con la utilización del acelerador del Centro del Acelerador Lineal de Stanford y una máquina de difusión de su propio diseño, Hofstadter pudo realizar mediciones de gran precisión del tamaño y configuración del protón y del neutrón. Mostró que ambos constan de un núcleo de carga denso rodeado por dos capas entremezcladas de nubes mesónicas. Hofstadter compartió en 1961 el Premio Nobel de Física con Rudolf Ludwig Mössbauer.

Extractions: Hofstadter studoval na Princetonské universitì, kde v roce 1938 získal titul Ph.D. Bìhem druhé svìtové války byl zamìstnán jako fyzik, který vyvíjel rozbuku do protiletadlových støel pro Národní úøad standardù. V roce 1946 se stal zamìstnancem university v Princetonu, kde se zabýval studiem infraèervených paprskù, fotovodivostí a krystalovými a scintilaèními èítaèi. Hofstadter uèil v letech 1950 a 1985 na Stanfordské universitì. Ve Standfordu pouíval k detekci èástic jádra lineární elektronový urychlovaè. V té dobì byly protony, neutrony i elektrony povaovány za bezstrukturní èástice. Hofstadter objevil, e protony a neutrony mají koneènou velikost a tvar. Byl schopen pøesnì urèit velikost protonu a neutronu a jako první nalezl první konzistentní obraz struktury atomového jádra. Objevil, e protony i neutrony jsou sloeny z centrálního jádra, které je kladnì nabité a je obklopené dvojitým oblakem pí-mesonù. V protonu jsou oba mraky mezonù nabity kladnì, kdeto v neutronu je vnitøní oblak nabit zápornì, tudí je výsledný náboj neutronu roven nule.

Extractions: R OBERT HOFSTADTER WAS BORN in New York City, educated on the East Coast, but spent most of his academic career at Stanford University. He is best known for his work on determining the distribution of charge and magnetic moment in the nuclei of atoms and of the nucleons themselves, for which he was awarded a Nobel Prize in 1961. He extended the work done in the early part of the twentieth century by Ernest Rutherford, who had shown that atoms were composite, containing electrons and a nucleus many thousands of times smaller than the atom. Rutherford discovered this by scattering alpha particles from thin metal foils of the elements and measuring the number of particles scattered as a function of the angle. The surprisingly large number of particles that were scattered through large angles could only be explained by collisions with a heavy, very small, perhaps point-like, positively charged object, which he called the nucleus. Some 40 years later Hofstadter determined the internal structure of such nuclei by scattering high-energy electrons from thin targets and measuring the distribution of the number of these electrons as a function of angle. In these experiments he built on earlier work by others on electron-electron scattering from atoms and electron-nuclear scattering by Hanson, Lyman, and Scott at Illinois done at lower energies in 1951. Hofstadter showed that the nuclei had internal structure extending over a small but measurable distance and that the heavier nuclei had a relatively uniform density within a thin surface skin. The Nobel committee considered this to be the first "reasonably consistent" picture of the structure of the nucleus.
