Calculations of P and T -odd interaction constants of alkaline-earth monofluorides using KRCI method

Abstract

We have reported the results of ab initio calculations of parity- and time- reversal -odd interaction constants for the ground state of alkaline-earth monofluorides. The Kramers-restricted configuration interaction method limited to single and double excitations in conjunction with the quadruple zeta quality basis sets have been employed to perform these 4-component relativistic calculations. The results are compared with the existing semi-empirical and other theoretical results, wherever available.
