Chemical Detection of Helium formed in Beryllium by Gamma Rays

Abstract

SOME time ago, we showed1 that micro-analytical methods are sensitive enough to identify spectro-scopically and to measure the helium artificially produced by slow neutrons in boron. This reaction has been fully investigated by physical methods2, so that chemistry can merely help in its quantitative study ; but there are other processes of artificial disintegration where apparently at present only microchemical methods can decide between different possibilities.
