/sup 111/Ag utilizing the (THe, pnel) reaction: A rotational nucleus with intermediate deformation

The structure of /sup 111/Ag was studied using the /sup 110/Pd(THe, pnel) /sup 111/Ag reaction, which has populated an essentially complete set of low-energy states. The proton exit channel was isolated from competing reaction channels by operating el-ray detectors in coincidence with a large-solid-angle proton detector. The experiments included el-ray excitation functions, el-ray angular distributions, and el-el coincidences. Four rotational bands have been identified. A symmetric particle-rotor model has been used to interpret these bands, and the model has identified other rotational features as well. A tentative interpretation of several nonrotational states is presented, suggesting that the mixing between rotational and nonrotational states is minimal.
