Abstract

The information on the coexistence of deformed intruder states and normal spherical hole-core coupled states in odd-mass Ag nuclei has been extended to the neutron-rich isotopes Ag66113 and Ag68115. Data have been obtained from an investigation of the γ rays following the β decay of the Pd113,115 precursors. A minimum for the excitation energy of the intruder states occurs in Ag66113, exactly at neutron midshell. The properties of the intruder states in Ag109,111,113,115 are discussed and a description in the framework of the interacting-boson-fermion model is presented.
