摘要：

Semi-classical calculations are carried out for the processes of associative detachment H + H- -> H2 + e and of collisional detachment H + H- -> H + H + e based upon values of the real and imaginary parts of the complex adiabatic potential computed by Bardsley, Herzenberg and Mandl and upon semi-empirical values derived by Chen and Peacher. The experimental data at high velocities lend support to the theoretical predictions of Bardsley et al., but the argument is inconclusive because of possible non-adiabatic contributions. It is pointed out that it may be possible to resolve the question by an experimental investigation of isotope effects at high velocities.
