摘要
利用通道规律，并考虑了转动分布对跃迁峰型的影响，对测量得到的绝对氢分子光吸收谱进行了分析．文中逐个确定了１１０—１５０ｅＶ各振动态的振子强度，并得到了Ｂ′１Σ＋ｕ的解离强度．同时，利用多重散射Ｘα自洽场方法计算了氢分子分立区和连续区（１１０—１９０ｅＶ）的光吸收谱．通过计算值和实验绝对测量值的比较可以说明，在自洽层次。
Abstract By considering channel characters and thermal distribution of the
rotational levels, experimentally determined absolute photoabsorption spectrum of molecular
hydrogen have been analysed: these vibronic oscillator strengths in the region of 11 0 15 0eV
are determined, the total photodissociation of B′ 1Σ + u is also obtained. Meanwhile, the
photoabsorption spectrum in the valence and continuum regions (11 0 19 0eV) of molecular
hydrogen has been calculated based on multi scattering self consistent field. The theoretical
calculations are in good agreement with experimental results.
