Abstract
The coupled integro-differential equations for electron collisions with an N-electron ion may be solved at energies which give bound states for the (N+1)-electron system. Results are obtained for the 1P0 series in C2+, including the configurations 1s22snp, 1s22pn's, 1s22pn"d and 1s22s2p. The 1s, 2s and 2p radial functions are calculated for C3+ and the np, n's and n"d radial functions are solutions of the coupled integro-differential equations.Keywords
