...charge-either north or south. That charge, said Dirac, would be 68.5 times as strong as the charge on an electron. Or it would be some multiple of 68.5-say, 137. Scientists had good reason to respect Dirac's reasoning. He had earlier predicted the existence of a positron, or positively charged counterpart of the electron. The positron was subsequently discovered during cosmic-ray experiments in 1932, but the monopole proved more elusive. Physicists searched for it without success in everything from ocean-floor minerals to meteorites and moon rocks...
...Nature, Astrophysicist Robert M. Hjellming of the National Radio Astronomy Observatory at Green Bank, W. Va., argues the possibility of holes that are the complete antithesis of black holes. Such opposites are common enough-for example, the negatively charged electron and its antimatter version, the positively charged positron. But Hjellming's white holes are more than simply mirror images of black holes. They are sources of matter that could literally come from out of this world...
Physicists working on Bypass succeeded last month in producing and storing a high-energy positron beam. They have not yet been able to project positron...
...engineers and technicians--working under Karl Strauch, professor of Physics, and James K. Walker, assistant professor of Physics--who have been studying the influence of electrical charges on one another at exceedingly small distances. To do so, the scientists have used the beam from the accelerator to produce electron-positron pairs...
...result was a proposal last summer for a $650,000 "positron injector" which would send a stream of positrons into the accelerator in the opposite direction. The two streams could be made to collide at a given point...
