Coherence and correlation parameters for thed 3 ? u ? (v=0,1,2,3;N=1) states of H2

Abstract

We have applied the density matrix formalism and the distorted-wave approximation to calculate the Stokes parameters for thed3 Πu− (v=0,1,2,3;N=1) states of H2 excited from the X1 ∑g+ (v=0,N=1) state by electron impact at the incident energies ranging from 15 to 40 eV. Our results show that these parameters are nearly independent of the vibrational quantum number of the excited states. However, the polarization of the radiation emitted by the target in the subsequent decay process increases with increasing incident energies.
