Population and decay of the HenICl(β1) clusters

Abstract

The letter presents the results of studies of population and decay of the {2,0}He2ICl(β1,vβ = 0) and {1,1}He2ICl(β1,vβ = 0) clusters. Action, pump–probe and luminescence excitation spectra as well as luminescence spectra themselves have been measured. The T-shaped HeICl(E,vE = 0 andD′,vD′ = 0) complex luminescence has been observed when the {2,0}He2ICl(β1,vβ = 0) cluster is populated. It has been shown that a population of the {1,1}He2ICl(A,13,nA) cluster at the energy higher than its dissociation threshold is accompanied by the T-shaped HeICl(A,13,nA) formation.
