Find the following: <r> for the 2p0 <r2> for the 2p1
Explain why each of the following integrals must be 0 when the functions are hydrogen-like wavefunctions: <2p1|Lz|3p-1> and <2p0|Lz|2p0> Show that taking the lithium spin orbitals in a Slater determinant as 1sa, 1sb, and 1s(c1a+c2b) where c1 and c2 are constants gives a wavefunction that equals zero. Tthe a and b are alp
