我们从莱曼线和巴尔默线的发射截面估计了分子氢解离成激发态原子时产生激发态氢原子的截面。我们建立了等离子体中基态氢分子、激发态氢原子和质子系统的碰撞辐射模型，并计算了激发态的居群密度分布。巴尔默系列谱线的发射谱线强度比与电子密度的关系被绘制出来。我们期望这些结果对含有氢分子的等离子体的研究有用，例如发生在托卡马克等离子体的外区。
We have estimated the cross section for the production of excited hydrogen atoms from the emission cross sections for Lyman and Balmer lines when molecular hydrogen is dissociated into excited atoms. We have constructed a collisional‐radiative model for the system of ground‐state hydrogen molecules, excited hydrogen atoms, and protons, in a plasma and have calculated the population density distribution of the excited states. The resulting emission‐line intensity ratios for the Balmer series lines are plotted against electron density. We expect these results to be useful for studies of plasmas containing molecular hydrogen, such as occur in the outer region of tokamak plasmas.
