In this paper, we report on the effects of LS term dependence on radiative rates and electron-impact excitation cross sections in He-like ions. In particular, we examine the variation of the 2p orbital between the 1s2p 3P and 1s2p 1P terms in Li+, C4+, F7+, and Mg10+. We find that for transitions between the 1s2p 1P1 level and the ground state, term dependence causes a variation in both the radiative rate and the excitation cross section at nearly the twenty percent level; however, by Mg10+ this variation is less than five percent.
