Measurements of the polarization of elastically scattered protons have been carried out to determine the total angular momenta of the isobaric analogues of the ground state and of the first two p-states in 145Sm. They were found to be Jπ = 7 2-, 3 2- and 1 2-, respectively. The assignment of Jπ = 1 2- for the second l = 1 state is disagreement with previous assignments. © 1969.
