Complex L2 calculations of bound states and resonances of HCO and DCO

We report new calculations of bound states and resonances of HCO and DCO for total angular momenta zero and 1, using a modified ab initio potential, which was previously adjusted to improve agreement with experiment for bound states of HCO. The method to calculate the resonances is based on a diagonalization of a complex Hamiltonian, which is given by the full-dimensional real Hamiltonian plus an optical potential. The new calculations focus on comparisons with new experiments on the bound states and resonances of DCO, as well as with previous and new experimental data on HCO bound states and resonances.
