Condensation of Pure He(3) and Its Vapor Pressures Between 1.2 Deg. and Its Critical Point,
Abstract
On October 13, 1948 the authors succeeded in condensing pure He(3), that was prepared by E. S. Robinson and E. M. Potter of the laboratory. The isotope was 'grown' from pure tritium solutions by beta decay of the tritium. The latter was initially separated from traces of He(4) by passage through a palladium valve. The He(3) was purified by absorption of H(2) and T(2) in uranium, followed by repeated successive passages over (1) hot CuO followed by a liquid air trap, and (2) hot Ca, thus removing all other impurities except the rare gases.
