摘　　要：本文利用由RKR方法计算得到的锂分子2~3∏_g态和a^3∑_u^+态(束缚部分)的势能曲线求解振动薛定谔方程,获得了2~3∏_9—a^3∑_u^+跃迁的F-C因子,自发辐射系数,进而计算了该跃迁的荧光强度和受激辐射带强度的光谱分布,其结果与实验测得的由双光子激发锂分子产生的受激扩散带辐射相吻合.The F-C factors, spontaneous radiation coefficients and fluorescence spectra corresponding to the 23∏g-as∑u+ transition in Li2 were calculated by the calculated RKR potential curves of the 23∏g and a3∑u+ states and soluting of the molecular vibrational schrodinger equation, thereby following the spectra of diffuse band stimulated radiation were gotten. The calculated results wore a match for the experiment in which diifuse band stimulated radiation was generated by two-photon exciting Li2.
