低温HD + $ortho$ -/ $para$ -H $_2$非弹性散射的天体物理研究
Low temperature HD + $ortho$-/$para$-H$_2$ inelastic scattering of astrophysical interest
摘要:
计算了低温下HD + $ortho$ -/$para$ -H $_2$转动能量转移碰撞的态选择总截面和热速率系数:2 K $\lesssim$ T $\lesssim$ 300 K.一个改进的H $_2$ -H $_2$势能面(PES)的Hinde设计用于这种纯量子力学动力学计算。HD + $ortho$ -/$para$ -H $_2$散射问题和以前的计算与使用其他旧PES的新结果的比较,并进行了讨论。
英文摘要:
State-selected total cross sections and thermal rate coefficients are computed for the HD + $ortho$-/$para$-H$_2$ rotational energy transfer collision at low temperatures: 2 K $\lesssim$ T $\lesssim$ 300 K. A modified H$_2$-H$_2$ potential energy surface (PES) devised by Hinde is used for this pure quantum-mechanical dynamical computation. A comparison of the new results for the HD + $ortho$-/$para$-H$_2$ scattering problem and previous calculations computed with the use of other older PESs is presented and discussed.
