Abstract

It is shown that, in dense plasmas, dielectronic capture into doubly excited ionic states followed by the ladderlike excitation-ionization chain becomes important in the excitation-ionization process of ions. For an example of a hydrogenlike ion, its contribution to the excitation 1s..-->..2s, 2p and also to the ionization has been evaluated by the method of the quasisteady-state solution to the rate equations. The increase is found to be substantial, i.e., by more than a factor of 2 both for the excitation and ionization rate coefficients.
离子在致密等离子体中的新激发和电离机制:自电离态的作用
结果表明,在致密等离子体中,介电子捕获到双激离子态,然后形成阶梯状的激离链,是离子激离过程的重要组成部分。以类氢离子为例,它对激发的贡献是…->…用速率方程的准稳态解的方法计算了2s, 2p和电离态。发现这种增加是相当大的,即激发速率系数和电离速率系数都增加了2倍以上。
