Neutron Country. All winter, Dr. John Simpson of the University of Chicago's Institute for Nuclear Studies flew back & forth between the northern U.S. and Lima, Peru, in a Navy Bag packed with special instruments. He was hunting neutrons, those subtle particles that slip into atomic nuclei and often disrupt them with bangs of radiation. He found plenty of neutrons. The higher he flew the more he found. They were not invaders from space, his studies told him, but were spattered out of atmospheric nuclei struck by cosmic rays...
...when a big, detonating "fireball" from space streaked across the Midwest last Feb. 18, the Chicago Institute for Nuclear Studies wanted a sample of it, and Dr. Lincoln LaPaz, meteorite hunter of the University of New Mexico, set out to trace one. It took him two months to find several fragments in Norton County, Kans. One of them weighed 130 Ibs. and was made of stony material mixed with globules of nickel and iron...
This figure (6 BEV) has a thrilling, musical ring to the ears of nuclear physicists. The 184-inch cyclotron at Berkeley generates only about 350 MEV (million electron volts). With this comparatively puny force, it creates mesons, the mysterious particles knocked out of matter by cosmic rays from space. The new cyclotron will give its protons so much energy that they will act like the "primary" cosmic rays themselves, which slam through the earth's atmosphere and plunge deep into the ground. These wild invaders from space have never before been caged in laboratories. No one can guess what...
Physicist Enrico Fermi, Chicago Nobel Prizewinner who started the first nuclear chain reaction, said last week: "I know of nothing that can be developed into a radioactive cloud without the bomb." Other physicists in a position to know preferred to keep their mouths shut...
...Joliot-Curie, daughter of famed Physicist Marie Curie, is a distinguished nuclear physicist in her own right, a Nobel prizewinner and the wife of a Communist. Like her husband, Frederic, she is also a member of France's Atomic Research Commission. Late one afternoon last week, Mme. Curie stepped off an Air France plane at La Guardia Field. Waiting to meet her was Dr. Edward Barsky, chairman of the Communist-front Joint Anti-Fascist Refugee Committee, under whose auspices Mme. Curie was to lecture...
