摘要: 指出在计算Landau体系的光致跃迁概率时,计算矩阵元xm,k.ym,k的积分变量应是dτ=dxdy,,而不是dτ=dxdydpy同时还指出,应将矩阵元ym,k表示为ympy,kpy^0以,修正了Landau体系的光致跃迁选择定则。

关键词: Landau体系, 光致跃迁, 矩阵元

Abstract: The fact that when computing transition of Landau system due to light, the integration variable of computing matrix element xmk,k, ym,k isn't dτ = dxdydp but dτ = dxdy is indicated, and that the matrix element Ym,k should be expressed as ympy,kpy^0, is also indicated, and the transition selection principle of Landau system due to light is revised.

Key words: Landau system, transition due to light, matrix element
