On the effect of cascade transitions after electron-impact excitation of Zn by spin-polarized electrons

Abstract

We investigate the possible effect of cascade transitions from the (4s5p)3P0,1,2 states to the (4s5s)3S1 state of Zn. Our calculations suggest that the excitation cross sections and the polarization of the cascade radiation cannot explain the serious controversy between two existing experimental datasets below the cascade threshold and raise additional questions regarding the measurements at higher energies.
