Abstract : The isotopic abundance of He(3) in one sample each of "well" helium and "atmospheric" helium has been measured by detecting the He(3)(n,p)H(3) 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 He(3) content deduced using the known ratio of the He(3) and N disintegration cross sections. jg p.2
