Died. Walther Wilhelm Bothe, 66, Prussian-born nuclear physicist who in 1930 produced unexpected radiation by bombarding beryllium with alpha particles, and thus led to the discovery of the neutron, in 1954 won the Nobel Prize for physics for his development and use of the "coincidence method" of measuring time with billionth-of-a-second accuracy; after long illness; in Heidelberg, West Germany...
...magnets are gentle, harmless things, but when a magnetic field gets really intense, it acts like a high explosive. Physicists H. P. Furth of the University of California, M. A. Levine of the Air Force Cambridge Research Center, and R. W. Waniek of Harvard showed a ring of hard beryllium copper that had been expanded plastically by a magnetic field, even though it was surrounded by steel many inches thick...
...identification nearly a year ago of the antiproton (TIME, Oct. 31), the work was done with the Berkeley Bevatron, the world's most powerful particle accelerator, and a long train of auxiliary apparatus. The Bevatron's beam of 6.2 billion-volt protons was shot into a beryllium target. Out of the target came a secondary beam of assorted atomic debris. The particles with a negative charge, separated from the rest by the Bevatron's strong magnetic field, were mostly mesons. Among them were a few antiprotons (negative protons) formed when the Bevatron's powerful projectiles smashed...
...cost of reactor materials, e.g., zirconium, beryllium and heavy water, must be greatly reduced...
...diameter. When they reach the outside spiral, they are moving at 140,000 miles per second (more than, seven-tenths of the speed of light), and carry 385 million electron volts of energy. At the peak of their speed and power, the protons hit a block of beryllium. Out of it sprays a swarm of "pi mesons"-elusive, still-mysterious particles first found in cosmic rays...
