Week 5 Orbital Angular Momentum Part II Flashcards
1
Q
Give one of the angular momentum component operator equations
A
Lz = xpy - ypx Lx = ypz - zpy Ly = zpx - xpz
2
Q
what is true of L
A
can’t know any of the components of L simultaneously
3
Q
why is L^2 important
A
Components (Lz etc) can commute with L^2
4
Q
what is the L component eigenvalue
A
Lz = mħ
where m is any integer
5
Q
what is the L^2 eigenvalue
A
L^2 = λħ^2
where λ is > 0
