Lifetime measurement of some excited states belonging to the 3p4nd (n=4–6) configuration of ArII

Abstract

The radiative lifetimes of eight levels belonging to the 3p 4 nd (n=4-6) configuration of ArII have been measured using high frequency deflection technique together with a delayed coincidence single photon counting arrangement. Lifetimes of some of the levels have been measured for the first time. The results have been compared with other experimental and theoretical values.
