(7.1-3) M 2c=±l B (CGS) MB是Bohr磁子 由式(71-2),电子自旋磁矩和自旋角动量之比为 M e M e (SD (CGS) (7.1-4) C 这个比值称为电子自旋的回转磁比率.我们知道轨道角动量和轨道磁 矩的关系是 L M (CGS) (7.1-5 2 即轨道运动的回转磁比率是-(SD;-2(CGS),因而自旋回转磁比 率等于轨道运动回转磁比率的两倍 ●Fist●Prev·Next●Last● Go Back● Full Screen●cose●Quit• First • Prev • Next • Last • Go Back • Full Screen • Close • Quit §7.1. >fg^ 7/71 KUü‡êŠ: MSz = ± e~ 2µ = ±MB, (SI), MSz = ± e~ 2µc = ±MB, (CGS) (7.1-3) MB ´.
