Abstract

By using heavy-ion induced fusion-evaporation reactions at the on-line mass separator of GSI, decay properties of neutron-deficient isotopes between 56Ni and 100Sn were investigated. Recent experimental results will be presented and discussed, with particular emphasis on the role of masses, Q values and separation energies.
