【 摘 要 】

Radiative association of metastable helium He(23P) with lithium ions is theoretically investigated on the triplet-sigma manifold. Cross-sections and the corresponding rate coefficients for spontaneous and stimulated processes are calculated. Results are compared to other radiative and non-radiative processes in collisions of metastable helium with lithium ions.
