[SOLVED] QM: Spin -orbit coupling: Solve [(L.S), L]
Griffiths problem 6.16
Solve the following commutators (he lists a bunch but i can't get even the first one)
(a) [(L.S) , L]
(b) [(L.S) , S]
(c) [(L.S) , L^2]
there's a few more, but i think if i get the idea then...
[SOLVED] Hyperfine splitting of deuterium
Calculate the wavelength of the photon emitted under a hyperfine transition in the ground state (n=1) of deuterium. Deuterium is a proton and a neutron in the nucleus, but still one electron. The spin of deuterium is 1.
Hey, I've been reading on this site for a week of so now, and just wanted to say thanks for all your contributions. Very helpfull!
