Abstract
Helium gas was excited by 1.15 Mev protons from a Van
de Graaff generator. Intensity of the radiation spectrum
versus pressure data were recorded and plotted for the
²F- ²D transition in He II (4686 A) . Through use of theoretical
equations and experimental data, the collisional
de-excitation rate coefficient, K, was determined to be
(5.03 ± 0.21) x 10ˉ¹² cm³ secˉ¹ . Suggested experimental
procedure is discussed for continuation of this investigation
using electron excitation.
