In the ground state of the H atom, n = 1,l=0 R_1,0 (r)=2/(a^(3/2) ) e^(-ρ/2), Y_0,0=1/√4π
Write down ψ_(n,l,m) (r,θ,ϕ)
What is the expectation value of the radial momentum, which you may evaluate in the reduced ρ coordinate, i.e., obtain the expectation value of the p =ℏ/i d/dρ. Does the answer seem to contradict with the Bohr model?
