Question: spinorbit interaction question the answer to the first bit is...
Spin-orbit interaction question. The answer to the first bit is j=7/2, 9/2 with energy splitting (9/2)*A*(h-bar)^2. The splitting in the second part is 5.2*10^-5 eV. Please can you explain how to get these answers? Particularly why j takes those values, that’s the part I really don’t get.
In this second case the j values are 3/2 and 5/2, why is this case different?
