【 摘 要 】

This study is devoted to the theoretical investigation of the quasimolecular emission of Xe∗-He and Kr∗-He collision pairs near the Xe (5p56s1,3P1- 5p6 1S0) and Kr (4p55s1,3P1- 4p6 1S0) resonance atomic lines. The potential curves of the quasimolecules Xe(5p56s) + He and Kr(4p55s) + He have been obtained with the use of the effective Hamiltonian and pseudopotential methods. Based on these potential curves the processes of quasimolecular emission of Xe∗+He and Kr∗+He mixtures have been considered and the spectral distributions I(HΔω) of photons emitted have been obtained in the framework of quasistatic approximation.
