Some intensity measurements on the band spectrum of helium (He 2 )

Abstract

The Summation Rule of Burger and Dorgelo in the hands of R. H. Fowler, Mulliken, Dieke and others, has led to the rapid development of theoretical intensity relations. For some time only qualitative data were available, but with the development of intensity measurement technique, quantitative data are accumulating to test the theoretical predictions. Work of a quantitative nature on the band spectrum of Helium has been carried out by Childs, Fujioka, and Read, who have made measurements on the 4650 band, the "decoupling bands," and the λ 6400 band respectively.
