分子多光子共振吸收的理论研究

THEORETICAL STUDY OF MULTIPHOTON DISSOCIATION FOR RESONANT DECAY WIDTHS AND RESONANT ENERGIES

首先利用Floquet理论得到共振态的本征函数,再通过求解束缚态与连续态的耦合矩阵而得到束缚态的解离几率,最后得到任一束缚态通过耦合而解离的解离几率及衰变宽度等,利用我们得到的公式,对不转动的双原子分子及双原子分子模型进行了计算,在外场不是特别强的情况下,得到了一些很好的结果。

First the resonant eigenfunctions are obtained by using the Floquet theory. Then the dissociation probabilities are gained by solving the coupled matrix of bound state with continunm state. From the above studies, we have got the decay widths of bound states, the resonant energy positions and dissociation probabilities of bound states. Using the quasi-classical theo-ry and above formulas, we have eonducted some calaulation about decay widths of nonrotat-ing, diatomic molecules in the ground electronic state absorbing one photon or two photons.
