Hi.
please help me. i realy need a quick reply.
I study the bandStructure of SrS with and without Spinorbit but I have no enough information to explanation it.
the Sr has([kr] 4s2 4p6 5s2) and S has([Ne] 3s2 3p4) Structure. I attache the bandStructure of this compound calculated using pseudopotential(dotline is with spinorbit and solid line without Spinorbit effect).
the lowest band is (4s Sr) the second band is (4p Sr) the , third line is (3s S) and the band below the fermi is (3p s).
I have two question?
1.degeneracy in (4p Sr)band is 3fold or 6fold?
2. If the degeneracy for 3band of p like is 3fold, why we have 3fold degeneracy in [itex]\Gamma[/itex] point but 2fold in [itex]X[/itex] point in absent of Spinorbit? I mean in absent of spinorbit, what effect splits degeneracy(crystal field)?
3. I don't know how use of H=[1]/[2m^{2}C^{2}r] [dV]/[dr] L.S
to interpret difference in strong splitting between 4p Sr and 3p S?
please i need a quick reply.
