摘要
We present thermally averaged collision strengths fur electron induced transitions in helium from 1s(2) S-1, 1s2s: S-1,S-3, 1s2p P-3 to higher lying terms 1snl L-1,L-3 with eta less than or equal to 5. Results are tabulated as functions of temperature in the range 3.75 less than or equal to logT less than or equal to 5.75. Cross sections are calculated using the convergent close-coupling (CCC) method.
