摘要/Abstract

摘要： 基于碱土金属原子Be和分子CO精确的相互作用势，采用对数-导数传播子方法和非耦合角动量表象，计算低和超低能碰撞条件下Be-CO体系在电场中的碰撞动力学，获得若干电场中碰撞体系低场追索态的弹性和非弹性碰撞截面，预测Be原子感应冷却CO分子的可行性.

关键词: Be-CO体系, 冷碰撞, 感应冷却

Abstract: With accurate interaction potential surface, Be-CO Hamiltonian equation is solved by numerical methods. Cold collision dynamics for Be atom and CO molecule is investigated by quantum scattering calculations. Influence of applying electric field on elastic and inelastic collisional cross-sections of low-field-seeking state at cold and ultracold temperatures are explored. It provides theoretical support for experimental sample molecules.

Key words: Be-CO complex, cold collision, sympathetic cooling
