中文摘要
9408879元 研究了几种模型原子和分子系统中混沌散射的量子分支。 用多种半经典方法研究了长寿命碰撞复合物形成的新机制、电子- He ~+周期轨道、与化学键相对应的相空间结构以及电子场显微镜金属针尖附近HeRh ~(2+)的同位素效应. ***
英文摘要
9408879 Yuan The quantum ramifications of chaotic scattering in several model atomic and molecular systems is investigated. New mechanisms for the formation of long-lived collision complexes, e- He+ periodic orbits, phase space structures corresponding to chemical bonding and isotope effects on HeRh2+ near the metallic tip of an electron field microscope are studied in using a variety of semiclassical approaches. ***
