E(level): From least-squares fit to Eγ, for levels with depopulating gammas. Level energies, if without depopulating gammas, are from (t,α),(pol t,α).

Jπ(level): From a comparison between experimental and theoretical angular distributions of (t,α) cross sections, and from analyzing powers measured in the (pol t,α) reaction, except where otherwise noted. Nilsson orbitals were assigned mainly on the basis of systematics of the same orbitals in other odd-mass Re isotopes.
