Abstract
The recent assertion that shape coexistence occurs in the neutron-rich isotope implies that a state observed at 940 keV in a previous study is a rotational excitation of the deformed ground state. Here we use results from two intermediate-energy reactions to demonstrate that this state—assigned an energy of 971 keV in the present work—is indeed a rotational state. This result strengthens the case for shape coexistence in .
