摘要
用准相对论扭曲波方法系统的计算了Pb,Au,Ba,Mo,Ge类镍离子组态能级之间的电子碰撞激发强度Ω(nl-n′l′),3≤n≤7,4≤n′≤7,同时给出了高能极限的碰撞强度和外推到阈值的碰撞强度。用最小二乘样条方法拟合了全能域碰撞强度及热平均速率系数。对于一个激发过程。
Electron impact excitation collision strength Ω(nl-n′l′)(3≤n≤7,4≤n′≤7) among configuration average levels for the Ni like Ions Pb 54+ , Au 51+ ,Ba 28+ ,Mo 14+ ,Ge 4+ have been calcuated systematically using the quasirelativitic distorted wave methods. In addition, the collision strength in high limit have been calculated. The data for the collision strength or thermally averaged rate coefficient over the whole range of energy or temperature have been evaluated by a least squares spline fitting procedure. As a result, the collision strength with arbitrary electron energy and rate coefficient with arbitrary temperature can be determined by ten parameters.
