Abstract
Electron propagator theory is applied to calculating vertical electron affinities of the title molecules. Third order and outer valence approximation quasiparticle calculations with and without effective core potentials are compared for molecules with fourth period atoms. Discrepancies between the two sets of results are small and stimulate applications to fifth period analogs. Good agreement with experiment is obtained for all the molecules; a prediction for the still unmeasured electron affinity of SbH2 is made.Keywords
