Abstract

Through an in-beam study of the 15369 Tm84 nucleus we have identified the πh 2/511 /2νf 2/27 and πh 2/511 νf7/2h9/2 7-valence particle configurations up to their fully aligned spins of 47/2− and 51/2−. Shell model calculations predict that in the πh 2/511 νf7/2h9/2 configuration, contrary to the π 2/511 νf 2/27 case, the h11/2 proton seniority does not increase regularly with spin. This seniority inversion is verified by the data.
