Expectation values of quasibound states: Nuclear quadrupole coupling constants of BH in the (X)over-tilde(1)Sigma(+) and (B)over-tilde(1)Sigma(+) states

摘要

The B-10 and B-11 nuclear quadrupole coupling constants of the bound and quasibound rotation-vibrational levels of BH in the ground (X)over-tilde(1)Sigma(+) and double-minimum excited (B)over-tilde(1)Sigma(+) electronic states are evaluated using ab initio calculated potentials and electric field gradients. The predicted expectation values of the resonance states are found to be smooth continuations of those of the bound states, but their dependence on the rotational and vibrational quantum numbers differs from the standard Dunham-type polynomial dependences obtained for bound state constants.
