...bombarded the element beryllium with alpha particles. Something happened to the alpha particles. The particles contained four units of positive electricity (protons) and two of negative electricity (electrons) when they crashed into the beryllium. Two protons of an alpha particle seemed to cling to the nucleus of a beryllium atom (thereby theoretically transmuting that atom of beryllium into an atom of carbon). The particle's other two protons and the two electrons seemed changed into what Professor Bothe considered an artificial gamma ray, which like a light ray is an electromagnetic phenomenon...
...proton, which is 1,845 times as heavy as an electron, might make an electron its satellite. Such a simple system of one electron revolving around one proton makes up a common atom of hydrogen, simplest of the 92 elements. (Helium, next simplest, has an alpha particle for its core, two electrons for satellites. Other atoms have more protons, more electrons...
...Chadwick doubts that. Neutrons may be, because they have opposite poles, the long sought units of magnetism. Whatever they are, neutrons are fine things for physicists to play with and to guess about. They are, declared Lord Rutherford last week, the greatest discovery since the artificial disintegration of the atom...
...three isotopes, is comparable to a lot of lemons, oranges and grapefruit in a paper bag.' Dr. Bainbridge knew the weight of the whole, also the average weight of each piece of his "fruit," but (he assumed) not the weight of each individual piece. So he propelled the neon atoms through the chamber with an electric force, strong enough to blow the "bag" to pieces, ionize the atoms. Two huge electromagnets created a powerful magnetic field, which, like gravity pulling the fruit to earth, defleeted the course of the ionized atoms. Dr. Bainbridge snapped a picture. The lightest isotopes, like...
Last week three young Carnegie Institution men, Drs. Merle Anthony Tuve, Lawrence R. Hafstad and Odd Dahl, through the Physical Review, offered atom crackers a new, manageable howitzer. (They had first mentioned that piece of laboratory ordinance when the Association for the Advancement of Science met in Pasadena last June. Although the scientists could see little of the machine's effect, they nonetheless gave a $1,000 prize to the ingenious young men.) Their machine consists essentially of a tesla coil under oil and a cascading cathode tube. The coil builds up an electrical potential...
