利用了氢原子飞渡时间谱实验方法对处于高n主量子数里德堡态的氢原子与氦原子的分子束散射过程进行了高分辨研究.测量了H(n)+He→H(n′)+He散射过程的散射微分截面.实验结果表明,产物主要分布在前向散射方向,在侧向也有一定的分布.在前向和侧向存在大量的振荡结构.同时详细的研究也表明,在上述的散射过程中往前散射的方向上,氢原子里德堡态主量子数n的变化并不是很大.实验结果得到了为理论上精确研究高n主量子数里德堡态的氢原子与氦原子的散射动力学的一套精细的实验数据.
H (n) + He → H (n) was measured by using hydrogen atom time-of-flight spectroscopy to study the molecular beam scattering process of hydrogen atoms and helium atoms in the high n principal quantum Rydberg states. ’) + He Scattering Differential Cross Section The experimental results show that the products are mainly distributed in the direction of forward scattering and are also distributed laterally with a large number of oscillatory structures in the antecedent and the lateral directions, as well as detailed studies , The variation of the principal quantum number n of the Rydberg states in the hydrogen atom is not large in the direction of the forward scattering in the above scattering process.The experimental results have been obtained in order to theoretically study the Rydberg states with high n principal quantum numbers A set of detailed experimental data on the scattering kinetics of hydrogen atoms and helium atoms.
