摘要：

We present ab initio calculations of the W-A parameter of the P-odd spin-rotational Hamiltonian for a variety of diatomic molecules, including the group 2 and group 12 halides. The results were obtained by relativistic Dirac-Hartree-Fock and density functional theory approaches and corrected for core polarization effects. Strong enhancement of W-A is found for the group 12 diatomic halides, which should be helpful in future determination of the nuclear anapole moment.
