Ab initio MRD-CI calculations have been carried out on the ground and
the eight lowest excited electronic states of LiAr, correlating with e
xcited Li atom states up to 3d D-2. The ground (X (2) Sigma(2s)) and 2
(2) Sigma(+) (2p) electronic states are repulsive while the higher ex
cited states show shallow Rydberg minima. Rates of radiative bound-bou
nd and bound-free transitions have been also calculated.
