**1. Homework Statement**

find the 1st order correction for the 1st excited state with spin when the

H'=(eB0/2mc).Lz+2Sz z the direction

this proplem for the charge particleon sphere of radius R with magnatic field B

**2. Homework Equations**

l=1 m=0,1,-1

**3. ]The attempt at a solution[/b**

work out for the matrix 2x3 for

<Y10lH'lY10> SAME WITH SPIN DOWEN (-)

<Y11lH'lY11> ,,,,,,,,,

<Y1-1lH'lY1-1> ,,,,,,,,,,

And then find the digonal matrix solve it then find E01
