I believe the "SO" refers to some spin-orbit constant that GAMESS is missing. Are there any suggestions on how to fix this? > Well, a quick look at the code suggests that Spin orbital terms for atoms larger than Ar are not given. However, it seems to suggest that it should continue and assume they are zero, which for Ca they actually are. Could you please shows us the exact output for the failure?
