低碰撞能下Ne原子对LiH分子转动猝灭的研究
Rotational quenching of LiH by Ne at low energy
摘要
Abstract
Rotational quenching of LiH by Ne at low energy is first studied using the close coupling approach. At incident energies below 10-4 cm-1, the inelastic quenching cross sections are found to be inversely proportional to the velocity of the incoming Ne atom in agreement with Wigner threshold law, and the elastic cross sections are found to tend to constant limiting values. For a given energy, the total quenching cross sections decrease in general with increasing initial j. In the energy range Ej=0.01-100 cm-1 the elastic and inelastic cross sections show more complicated oscillational behaviors than other studied systems, due to the stronger anisotropy and two attractive wells of the interaction potential. The calculations show the quenching rate coefficients attain their values of the order of 10-11 cm3 s-1 at zero temperature limiting. For j=7 the rate coefficient presents upturn structure.关键词
