G. Igelmann et al., STRUCTURE AND IONIZATION-POTENTIALS OF CLUSTERS CONTAINING HEAVY-ELEMENTS .1. HOMONUCLEAR GROUP-V CLUSTERS UP TO HEXAMERS, Molecular physics, 80(2), 1993, pp. 325-339
Homonuclear clusters X(m) of heavy group V atoms (X = As, Sb) up to m
= 6 have been studied with valence ab initio self consistent field/con
figuration integration calculations using energy-adjusted pseudopotent
ials. Several structures have been investigated and results are given
for bond lengths (R(e)), atomization energies (D(e)) and vertical ioni
zation potentials of the ground states. Comparison with experimental a
nd other theoretical values is made where possible.
