✦ Synopsis

The results of ab initio calculations, using extended Gaussian basis sets and including correlation energy through a variety of means, provide strong support for the Mg(3p'tr,3p~" 3py). Ar(aE-) electronic-state assignment made by Massick and Breckenridge to spectral features in the resonant two-photon photoionization spectrum of vibrationally cold Mg(3s,3prr 3pg). Ar(ari) van der Waals complexes. The doubly excited Mg(3p'u,3p'rr 3p~). Ar(3,~-) state is found to be much more strongly bound than the singly excited Mg(3s,3p~r 3pj). Ar(3rI) state, which, in turn, is much more bound than the Mg(3s 2 ISo). Ar(3E +) ground state.
