Description
Recent experimental characterization of the subshell closure at N=32 in the Ca, Ti, and Cr isotones has stimulated shell-model calculations that indicated the possibility that the N=34 isotones of these same elements could exhibit characteristics of a shell closure, namely, a high energy for the first excited 2+ level. To that end, we have studied the decay of Sc56 produced in fragmentation reactions and identified new γ rays in the daughter N=34 isotone Ti56. The first 2+ level is found at an energy of 1127 keV, well below the expected position that would indicate the presence of an N=34 shell closure in Ti56
