...Colors. To measure this tiny quantity-less than a millionth of the energy needed to split the nucleus of an atom-the scientists devised an ingenious technique. Light from a 200-watt mercury vapor lamp was focused on a diffraction grating, which, like a prism, broke up the beam into its constituent rainbow of colors, its separate wave lengths of light. By rotating the grating to a carefully calculated angle, the scientists were able to reflect light of a single, specific wave length at a target. Knowing the wave length, they were able to determine precisely the energy...
...Will Fight." Whether or not his mood was affected by the military success, Premier Nguyen Cao Ky seemed to be in a freer and firmer state of mind about the political picture. Clad in a canary-yellow flight suit and sipping Jim Beam bourbon from a paper cup, he held an impromptu press conference at the Mekong Delta town of Can Tho. Ky said it would be at least a year before the new civilian government demanded by the Buddhists could be legally elected-and added that he expected to remain in power for that period. "Elections for a constituent...
...loss for rumors, exiles were brimming with an entirely new crop last week, hinting at possible coup attempts inside Haiti and new guerrilla invasions. To help pave the way, "The Voice of Haitian International Union," an exile group, buys time on a New York short-wave radio station to beam a half-hour news and conversation program into Haiti six days a week, poking fun at Duvalier. Castro is also taking to the air waves. "Duvalier has signed his own death warrant," Havana radio howls daily in Creole. "People of Haiti, rebel against the bloody gang in power...
Silver atoms that are caught in the penetrating beam capture neutrons and briefly become unstable isotopes, emitting gamma rays that can be recorded by the snooper's scintillation counter. Since silver isotopes, like radioactive atoms of other elements, have their own characteristic half life-or rate of decay-and emit gamma rays at a specific energy level, the snooper's detectors can distinguish them from atoms of other elements in the area that have also been made radioactive by the neutron beam...
...power to produce the snooper's stream of neutrons comes from a simple gasoline engine that runs a primitive type of particle accelerator. A beam of deuterium (or heavy hydrogen) particles emitted by the generator is directed against deuterium absorbed in a titanium target. As the deuterium particles collide, they release neutrons that are channeled into a beam that can cover a two-square-foot area of ground. The entire device, including the recording instruments, is small and light enough to be carried in the back of a Jeep. It has already been given trials in the field...
