Title: Ab initio calculation of the electron-nucleus scalar-pseudoscalar interaction constant W{sub s} in heavy polar molecules

Abstract

A fully relativistic restricted active space configuration interaction method is employed to compute the P,T-odd interaction constant W{sub s} for the ground ({sup 2}{sigma}{sub 1} at {sub {approx}}{sub sol{approx}} at {sub 2}) state of YbF and BaF molecules, which yield the results W{sub s}=-41.2 kHz and -9.7 kHz for YbF and BaF, respectively. Our present estimated results of the P,T-odd interaction constant W{sub s} is in reasonable agreement with previous calculations.
