摘要 通过函数变换将Dirac方程转化成拟Schrdinger方程,采用辛算法数值研究了理想等离子体环境对类氢原子(离子)的相对论能级和波函数的影响,结果表明,类氢原子(离子)的相对论电离能随着等离子体屏蔽的增强而减小,电离能关于j的简并被解除,导致相同l的能态互相靠近;等离子体屏蔽使得原子核对电子的束缚减弱,电子在空间上向远离原子核方向分布,并且幅度和相移都发生了变化. In this paper Dirac equation is converted into Schroedinger equation by function transformation and Hamiltonian equation is numerically solved by symplectic algorithm. Plasma screening effect on the relativity energy and wave function of hydrogen--like ions is studied in ideal plasmas. The results demonstrated that the ionization energy is decreased with increasing Debye potential, and the j degeneracy of the ionization energy is removed, which leads the energy states with same angular quantum number closer to each otherr the electron binding energy decreases with the plasma screening the wave functions are far away from the nucleus and the phase and amplitude are changed.
