consider the 1D quantum system with hamiltonian H0. Let H'(x,t)=H'(x) exp(iwt) +[H'(x)]* exp(-iwt) be a time dep perturbation suppose H0 describes an infinite potential and H'(x)=-eEx due to an oscillatory electrical field. Show that the transition is allowed only between two states with opposite parity. With s.o interaction, the Hamiltonian operator is H=H0+cL(dot)S.Let J=L+S be the total angular momentum operator. write the largest set of commuting operators(including H) 知道的人拜託教一下小弟吧 謝謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.114.202.35 ※ 編輯: Ihatenccu 來自: 140.114.202.35 (01/08 03:20)

也就是parity相反的state才有躍遷發生
