Depopulation of metastable helium He(2(1)S) by radiative association with hydrogen and lithium cations

Popis výsledku v původním jazyce

Depopulation of metastable He(2(1)S) by radiative association with hydrogen and lithium ions resulting in the formation of the HeH+ and HeLi+ molecular ions is investigated. Energy dependent cross-sections for spontaneous and stimulated processes on thespin-singlet manifold are calculated using a fully quantal approach and considering the association to rotational-vibrational states of the lowest singlet electronic states X-1 Sigma(+), A(1)Sigma(+), and B-1 Sigma(+) from the continuum states of the B-1Sigma(+) electronic state. Evaluation of the cross-sections is based on highly accurate quantum calculations taking into account all possible state-to-state transitions at thermal energies (for spontaneous association) or at higher background temperatures (stimulated association). The corresponding rate coefficients are then presented as functions of temperature. As expected calculations show that the rate coefficients for radiative association to the X and A states are several orders o
