Abstract
The structures of high spin states in neutron-deficient nuclei below the Sn isotope chain close to doubly-magic 100Sn are dominated by the interplay between proton holes in the g9/2 orbit and neutrons distributed over several single-particle orbits between the N = 50 and N = 82 shell closures. In nuclei close to 100Sn, this interplay can be either competitive, leading to well-separated families of either neutron particle or proton-hole configurations or cooperative at higher spin values, where both spin-aligned protons and neutrons contribute to the total angular momentum of the states. Given this situation, measurements of electromagnetic transition strengths are most appropriate to deduce information about the structure of high-spin states,namely to disentangle the contributions of the different configurations to the individual states. In the present work, detailed lifetime measurements in 101Ag and 104Cd have been performed, resulting in a large number of reduced electromagnetic transition strengths in both nuclei. These results as well as the level energies are compared to calculations within the interacting boson (fermion) plus broken pair model.
