Why exactly does helium-3 work better than helium-4 as regarding pumping of neon to a metastable level? Is it to do with its velocity distribution at a given temperature (faster than He-4), or redistribution of energy after collisions with neon atoms. There might be a better coincidence with levels due to helium hyperfine structure or isotope shift though this most likely work for only one line.

Just saw it was your special day. Happy Birthday. Have a great one.

Can't believe after all this time I never got or sent a friend request.
