Description
The electron impact excitation of He-like ions is studied using an equivalent-electron frozen-core approximation that was developed in an earlier paper on He. The resulting collision equations are solved using a five-state Coulomb exchange distorted-wave approximation that includes the dominant monopole exchange distorting potential exactly. Results are presented for scaled total collision strengths for all inelastic transitions between the states of Li+, Be2+, B3+, C4+, N5+, O6+, Ne8+, Mg10+, Si12+, Ca18+ and Fe24+, as well as for the infinite Z limit, for incident electron energies from threshold up to 4.0Z2 Ryd. The present results are in good agreement with those of close-coupling and distorted-wave calculations by other workers for transitions from the ground state in O6+. (author)
