Bound states of hydrogen-like ions in Debye plasma

在Debye屏蔽近似下,通过求解Schrdinger方程,计算了处于等离子体中的类氢离子的束缚态能量本征值与本征函数.研究了氢原子和类氢Fe^(25+)离子的nl(n=1-4,l=0-3)态能级随Debye屏蔽长度λ的变化规律.进一步,分析了等离子体屏蔽效应随主量子数n及角量子数l的变化规律,发现对于给定的l,等离子体屏蔽效应随主量子数n的增加而增大;对于给定的n,等离子体屏蔽效应随角量子数l的增大而减小.最后,我们分析了等离子体环境中类氢等电子序列离子的能级和波函数随屏蔽参数λ的变化规律,发现随着原子序数增大,等离子体屏蔽效应的影响逐渐变小.

The plasma screening effects on the energy levels and wave functions of hydrogen-like ions were estimated by using Debye model. The effects on n l (n=1-4,l= 0-3) energy levels and wave functions of hydrogen and Fe^(25+) ion versus screening lengths A have been analyzed. Furthermore, the screening effects versus quantum number n and l has been analyzed. The results show that the screening effects increasing as n increasing and decreasing as l increasing. Last, the Eigenenergies of isoelectronic series change against screening parameter A has been discussed, it's shown that the plasma screening effects are decreasing as nuclear charge increasing.
