| 摘 要： | 利用初态程函近似一连续扭曲波方法（CDW—EIS）研究了质子与B原子的碰撞电离过程。计算了入射粒子能量分别为100keV／u，1000keV／u，10000keV／u情况下的1s、2s、2p分波电离二阶微分截面及其总的二阶微分散射截面。并利用计算结果详细讨论和分析了软碰撞（SC）、电子俘获到入射粒子连续态（ECC）和两体相遇碰撞（BE）的碰撞电离机理，并对各分波二阶微分散射截面进行了比较。

| Abstract: | The H++B impact ionization process is investigated by using a continuum distorted wave method with the eikonal initial state(CDW-EIS) approximation.Double differential cross section for 1s,2s and 2p is calculated for projectile energies 100keV/u,1 000keV/u,10 000keV/u respectively.Based on the calculation result,this paper discusses and analyzes in detail the soft collision(SC),electron capture to the incident ion continuum(ECC) and the two-body collision encounter(BE) impact ionization mechanisms.It also c... |
