##J_+|j,m⟩ = ћ\sqrt{j(j+1)-m(m+1)} |j,m+1⟩##
##J_-|j,m⟩ = ћ\sqrt{j(j+1)-m(m-1)} |j,m-1⟩##
##J_z|j,m⟩ = mћ |j,m⟩##
##J^2|j,m⟩ = ћ^2j(j+1) |j,m⟩##
The Attempt at a Solution
Hi there,
For part a, the expression we're looking for is given, but I'm unsure as to how to derive it from the equation for ##J_+## given above. Any help would be very much appreciated.
