I looked into this, and there are some strange reactions: 1. 6Li + 7Li → 3 * 4He + n + Q (13.6 MeV) 2. 6Li + 7Li → 2 * 4He + t + p + Q (933 MeV) (!) 3. 6Li + 7Li → 4He + 3He + 2d + Q (1.8 GeV) (!) 4. 6Li + 6Li → 3 * 4He + Q (20.9 MeV) Reactions (1) and (2) have radioactive daughters, so that rules them out from the Lugano test. Reactions (2) and (3) have such huge Q values that I'm guessing the cross sections are be infinitesimal. Or I've made an error. Reaction (4) is very interesting. Since it yields three helium-4's, which are extremely stable, I wonder whether the cross section is nonnegligible. Eric
