Xe对NO(X)微分截面和非弹性散射中的碰撞诱导旋转准直

Differential Cross Sections and Collision-Induced Rotational Alignment in Inelastic Scattering of NO(X) by Xe

  • 摘要: 本文对NO(X)-Xe碰撞系统在碰撞能量为519 cm ^-1 , 测量了完全 \Lambda -双峰分解的微分截面和碰撞引起的旋转准直力矩.同时结合初始量子态选择, 使用六极杆的非均质电场, 借助量子态分辨的测量, 利用(1+1 ' )共振增强的多光子电离和速度离子成像.结果显示, 微分截面以及偏振相关的微分截面均显示与从头算势能面上进行的量子力学散射计算J. Kłos et al . J. Chem. Phys. \bf137 , 014312 (2012)一致.通过与准经典轨迹、硬壳势能的量子力学散射以及运动近端模型的比较, 评估了势能对所测微分截面和碰撞引起的旋转准直力矩的影响.

     

    Abstract: Fully \Lambda -doublet resolved differential cross sections and collision-induced rotational alignment moments have been measured for the NO(X)–Xe collision system at a collision energy of 519 cm ^-1 . The experiments combine initial quantum state selection, employing a hexapole inhomogeneous electric field, with quantum state resolved detection, using (1+1 ' ) resonantly enhanced multiphoton ionization and velocity map ion imaging. The differential cross sections and polarization dependent differential cross sections are shown to agree well with quantum mechanical scattering calculations performed on ab initio potential energy surfaces J. Kłos et al. J. Chem. Phys. 137 , 014312 (2012). By comparison with quasi-classical trajectory calculations, quantum mechanical scattering calculations on a hard-shell potential, and kinematic apse model calculations, the effects of the attractive part of the potential on the measured differential cross sections and collision-induced rotational alignment moments are assessed.
