摘要:

从二维和三维氢原子能级的精细结构表达式出发, 进行数值计算, 找到能级的精细结构数值的规律性。利用多媒体著作 工具Mult imedia ToolBook 计算能级并画出能级图和能级间距图, 进行比较。证实从三维降为二维能级降低而能级间距增大。从 基态到第一激发态、从第一激发态到第二激发态、从第二激发态到第三激发态二维能级间距分别是三维能级间距的4.74 、2.05 和1.61 倍。

Abstract:

Based on the fine st ructure representations of energy levels of a 2 -D and a 3 -D hy drogen atom , this paper has calculated the numerical values of the energy levels and draw n the figures of energy levels and the difference of energy levels of 2 -D and 3 -D hydrogen atom w ith Multimedia ToolBook .By comparing energy levels of a 2 -D hydrogen atom with those of a 3 -D hy drogen , it is found that the decrease in energy levels was caused by reduct ion of dimensionality , and spacing between energy levels increased .The spacing of energy levels of a 2 -D hydrogen atom from the ground state to the first ex ited state , the spacing of energy levels of a 2 -D hydrogen atom f rom the fi rst excited state to the second excited state and the spacing of energy levels of a 2 -D hydrogen atom f rom the second excited state to the third ex cited state is 4.74 , 2.05 and 1.61 times as that of a 3 -D hy drogen atom
