利用束缚态波函数的渐近形式和末态波函数的平面波形式研究了弱耦合等离子体对氢负离子光剥离截面的影响。德拜模型用于描述等离子体效应。所需的归一化常数是由三粒子系统的高精度、完全非绝热波函数确定的。在不同的德拜长度（D）范围内，从无限大（纯库仑）到D=1.0，计算了等离子体嵌入的H−离子的光剥离截面。
The effect of weakly coupled plasmas on photodetachment cross sections of the hydrogen negative ion is investigated by using the asymptotic from of the bound state wave function and a plane wave form for the final-state wave function. The Debye model is used to represent the plasma effects. The required normalization constant is determined from highly accurate, completely nonadiabatic wave functions for the three-particle systems. Photodetachment cross sections for the plasma-embedded H− ion are calculated for different Debye lengths (D) ranging from infinite (pure Coulomb) to D=1.0.
