Abstract
The structure of Ag111 was studied using the Pd110(3He, pnγ) Ag111 reaction, which has populated an essentially complete set of low-energy states. The proton exit channel was isolated from competing reaction channels by operating γ-ray detectors in coincidence with a large-solid-angle proton detector. The experiments included γ-ray excitation functions, γ-ray angular distributions, and γ-γ 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.
