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 and . Data have been obtained from an investigation of the γ rays following the decay of the precursors. A minimum for the excitation energy of the intruder states occurs in , exactly at neutron midshell. The properties of the intruder states in are discussed and a description in the framework of the interacting-boson-fermion model is presented.
