Abstract
Angular distributions have been measured for the (,) reaction at a bombarding energy of 15.0 MeV. Nine excited states below 6.02 MeV were observed. Comparison with microscopic two-particle distorted-wave Born approximation calculations yielded the following new assignments ( in MeV, ): 5.382, ; 5.603, ; 6.02, . Tentative assignments of (, , ) and (, ) were made to levels at 5.00 and 5.22 MeV, respectively. Spins of , , , and to the levels at 1.674, 3.568, 4.065, and 4.446 MeV were confirmed. The experimental spectrum of states below 6 MeV is compared with the results of an shell-model calculation using the Preedom-Wildenthal interaction matrix elements. Identification of possible core-excited states in is discussed.
