The stability of the negative ion of hydrogen (H^{-}) embedded in nonideal classical plasma has been studied by computing the ground state energy of the ion quite accurately. The interactions among the charged particles in plasma have been modelled by a pseudopotential, derived from a solution of Bogolyubov's hierarchy equations. An extensive basis set is employed in Rayleigh-Ritz variational method to compute the ground state energy of H^{-} for various values of plasma parameters. Effects of nonideality of plasma on the stability of the ion have been investigated in detail for a wide range of nonideality. Particular emphasis is made to compute accurately the critical values of the plasma screening parameters.

非理想经典等离子体中氢的负离子的稳定性。

通过相当精确地计算离子的基态能量，研究了嵌入非理想经典等离子体中的氢负离子（H ^ {-}）的稳定性。等离子体中带电粒子之间的相互作用已通过伪电位建模，该伪电位源自Bogolyubov层次方程​​的解。在Rayleigh-Ritz变分方法中采用了广泛的基础集，可针对各种等离子参数值计算H ^ {-}的基态能量。对于广泛的非理想性，已经详细研究了等离子体非理想性对离子稳定性的影响。特别强调要精确计算血浆筛选参数的临界值。
