摘要: A large cylindrical assembly of /sup 6/LiD was irradiated by neutrons from a high-intensity deuterium-tritium source. Small samples 6/Li, 7/Li, and 6/LiH, all encapsulated in lead, were positioned along the axis served as indicators for 4/He tritium production. The amount determined isotope dilution mass spectrometry while content 6/LiH wafers measured proportional counting gas samples. Careful comparison results with TART Monte Carlo calculations showed excellent agreement. For generation, experimental values 1.01 +. 0.06 times those calculations, ratio 1.055 0.07.
