Abstract
The decay of to has been investigated using ion-guide on-line mass separation and a 10 Ge-detector array to record coincidences to a detection limit well below that of former studies. Similarities are found in the -decay patterns of and of its isotone and also in the -ray decay rates and branchings of the corresponding levels in their respective daughters and . This indicates a persisting influence of the neutron shell closure for . The level structure of and the -feeding pattern are discussed in the frame of the interacting boson-fermion plus broken pair model and the microscopic quasiparticle phonon model.
