✦ Synopsis

For the Ca, SC, Ti and Y atoms calculations are performed for the ground states of the neutrals and the ground and several lowlying excited states of the negative ions. Overall the computed electron affinities are in good accord with experiment. The calculations show the rapid stabihzation of the 3d orbital relative to the 4p as the nuclear charge increases. The 'F" and 3DD terms are found to be close in energy in SC-and in Y -This confirms earlier speculation that some of the peaks in the photodetachment spectra of Y-originate from the bound excited 'F" term of Y-.
