J^π(level): From systematics of decoupled h_11/2 proton band in neighboring odd Pr nuclei. All assignments are considered as tentative, including that for the ground state, since no supporting experimental data are available for the assignment of multipolarities. For levels populated in high-spin studies, ascending order of spins with excitation energy is assumed based on yrast pattern of population

M(γ): From γ(θ) in (⁴⁰Ca,3p2nγ)
