Relativistic configuration-interaction study of the nuclear-spin-dependent parity-nonconservingelectron-nucleus interaction constant WA in BaF

摘要

A fully relativistic restricted active space configuration-interaction method is employed to compute theP-odd electron-nucleus interaction constant WA for the ground (~2Σ1/2)state of BaF, which yields the result ofWA = 160 Hz. Our present estimated result of the P-odd interaction constant WA is in reasonable agreementwith previous calculations. This result will be useful for the interpretation of the nuclear-spin-dependentparity-nonconservation experiment on BaF.
