摘要：

We investigate the pi(-) + H-2 -> gamma + n + n, pi(-) + He-3 -> gamma + H-3, pi(-) + He-3 -> gamma+n+d, pi(-) + He-3 -> gamma+n+n+p and pi(-) + H-3 -> gamma+n+n+n capture reactions using realistic two-nucleon and three-nucleon potentials and the single nucleon Kroll-Ruderman-type transition operator. We obtain predictions for the total capture rates for all these processes, calculating rigorously the initial and final nuclear states.
