Abstract:

The isotopic abundance of He3 in one sample each of well helium and atmospheric helium has been measured by detecting the He3n,pH3 disintegrations induced by thermal neutrons. The helium gas was put into a proportional counter, the disintegration rate compared to that with nitrogen in the counter, and the He3 content deduced using the known ratio of the He3 and N disintegration cross sections. jg p.2
