The variable charge, Coulomb-projected Born (VCCPB) approximation is applied to the calculation of cross sections for electron impact 11S–21S excitation in heliumlike ions (3 ≤ Z ≤ 8 and Si12+, Ca18+, and Fe24+). Differential and total cross sections have been reported for incident energies ranging from near threshold to five times threshold energy and are compared with other available theoretical estimates.
