文摘

Two theoretical methods are combined to make predictions on a molecule of interest in astrochemistry and related fields. A Cooper minimum in photoionization cross sections is predicted. Hybridization is important in several diffuse Dyson orbitals that correspond to addition of electrons to CaH+ to form highly excited states of CaH.
