论文摘要
NH $ _3 $从倒置上的能量转移到三胞胎的原子Rydberg州的原子，其主要量子数量$ n = 38 $是使用低于15 v/cm的电气场在in Intrabeam碰撞中的电场控制的。 1:19。 He原子是在亚稳定的1S2S $^3 $ s $ _1 $中制备的，在光束的尾随部分中的脉冲电排放中。重型NH $ _3 $和他被利用的较轻的逆转录的速度滑落，以$ \ sim70 $ m/s的质量碰撞速度进行碰撞研究。通过Rydberg-State选择性电场电离确定原子分子碰撞中的共振能量转移。已经将实验数据与基于影响参数方法的碰撞伙伴之间的共振偶极 - 偶极相互作用的理论模型进行了比较。
The resonant transfer of energy from the inversion sublevels in NH$_3$ to He atoms in triplet Rydberg states with principal quantum number $n=38$ has been controlled using electric fields below 15 V/cm in intrabeam collisions at translational temperatures of $\sim1$ K. The experiments were performed in pulsed supersonic beams of NH$_3$ seeded in He at a ratio of 1:19. The He atoms were prepared in the metastable 1s2s $^3$S$_1$ level in a pulsed electric discharge in the trailing part of the beams. The velocity slip between the heavy NH$_3$ and the lighter metastable He was exploited to perform collision studies at center-of-mass collision speeds of $\sim70$ m/s. Resonant energy transfer in the atom-molecule collisions was identified by Rydberg-state-selective electric-field ionization. The experimental data have been compared to a theoretical model of the resonant dipole-dipole interactions between the collision partners based on the impact parameter method.
