Relativistic configuration-interaction study of the nuclear-spin-dependent parity-nonconserving electron-nucleus interaction constant W-A in BaF

Abstract

A fully relativistic restricted active space configuration-interaction method is employed to compute the P-odd electron-nucleus interaction constant W-A for the ground ((2)Sigma(1/2)) state of BaF, which yields the result of W-A=160 Hz. Our present estimated result of the P-odd interaction constant W-A is in reasonable agreement with previous calculations. This result will be useful for the interpretation of the nuclear-spin-dependent parity-nonconservation experiment on BaF.
