WebMay 11, 2024 · 1 Answer. I'm not sure what you mean by "full states" but by definition a state ψ is invariant if R ψ = ψ for an arbitrary R ∈ SU (2). Since this implies. for every R ′, R ∈ SU (2), ψ spans a 1-dimensional representation of SU (2). There is only one 1-dimensional representation: it is the J = 0 (i.e. singlet) representation.
