Abstract
A unified theoretical approach is applied to calculate electron impact ioni zation cross sections for He-like ions(Be2+, B3+ and C4+). The 25 target st ates including 10 pseudostates are used in the R-matrix calculation. The cr oss sections are obtained as the sum of the cross sections into all states lying above the ionization threshold. The present results are in good agree ment with those of the experiment.
