Radiative Lifetimes for the A and C1σ+ States of the (SrK)+ Ion Molecular

We have investigated, in a previous work, the transition dipole moments (TDM) of the 13 (1)sigma(+) states of the (SrK)(+) molecular ion by using the ab initio method based on the pseudo-potential approach. The radiative lifetimes for all vibrational levels of A and C-1 sigma(+) have been calculated by using such transition dipole moments curves. We have included the bound-free emissions probabilities further to the bound-bound transitions. The bound-free emissions probabilities have been determined exactly, using the Franck-Condon approach, and then included in the total radiative lifetime. An important change has been observed for the higher excited vibrational levels in these lifetimes when the approximate evaluation breaks down. For the first time, the radiative lifetimes associated with the Aand C-1 sigma(+) excited state have been studied here.

Automated summary

In this study, the transition dipole moments of the 13 (1)sigma(+) states of the (SrK)(+) molecular ion were investigated using the ab initio method based on the pseudo-potential approach. The radiative lifetimes for all vibrational levels of A and C-1 sigma(+) were calculated using these transition dipole moment curves. The inclusion of bound-free emissions probabilities and the breakdown of the approximate evaluation revealed significant changes in the lifetimes of highly excited vibrational levels.
