利用赝态求和方法研究了模型势下锂原子的双光子跃迁速率。计算了不同德拜长度下2s-3s、2s-4s和2s-3d跃迁的跃迁振幅和吸收系数。在2s-3s跃迁的情况下，当德拜长度较小时，双光子透明消失。2s-3d跃迁发生反向入射。在这里，我们发现了一个双光子透明的德拜长度较低的值。这两种情况的发生是由于在等离子体环境中的能级移动。分析了共振增强频率和跃迁振幅的详细描述。
We have studied two-photon transition rates of atomic lithium within model potential by using the pseudostate summation approach. Transition amplitudes and absorption coefficients have been computed for 2s-3s, 2s-4s, and 2s-3d transitions with various Debye lengths. In the case of 2s-3s transition, two-photon transparency vanishes for smaller Debye length. Reverse incident occurred for 2s-3d transition. Here, we have found a two-photon transparency for lower values of Debye length. These two situations occur due to energy level shifting in the presence of a plasma environment. A detailed description of resonance enhancement frequency and transition amplitude has been analyzed.
