Abstract
The -odd interaction constant, , for the ground state of YbF and BaF molecules are calculated using the second-order many-body perturbation theory (MBPT) via -vector technique. The interaction constant reported here agrees favorably well with other correlated calculations. We also address the convergence behavior of with respect to the number of active orbitals used in the perturbative calculations.
