会聚线偏振强激光场中氢原子的能态变化

Structure distortion of hydrogen atom in a strong converging laser field of linear polarization

本文研究氢原子在会聚的线偏振强激光场中原子势的变化以及由此而引起的原子能级移位和波函数的空间扩展问题.结果表明,变化后的原子势等价于半径由外场决定而荷电量为核电荷的振荡球壳的势.在此势下,原子能级将变浅和分裂,波函数的空间分布将增大.

In this paper, we study the structure distortion, including the atomic potential, energy level and wavefunotion of hydrogen atom in a strong converging laser field of linear polarization. It is shown that the modified atomic potential is equal to a potential decided by an oscillating spherical surface with maximum radius of R0∝I1/2ω-2 and nuclear charges. With such a new potential, the atomic energy levels shallow and split, the wavefunction undergoes strectching in space drastically.
