IDENTIFICATION OF NEW NUCLEI AT AND BEYOND THE PROTON DRIP-LINE NEAR THE DOUBLY MAGIC NUCLEUS SN-100

The new neutron-deficient nuclei Sb-103, Sb-104, In-98, Pd-91, Rh-89, and Ru-87 have been identified among the quasifragmentation products o f a Sn-112 beam (63 MeV/nucleon). The fragment identification based on energy-loss, total kinetic energy, and time-of-flight measurements ha s been independently confined via observation of gamma radiation follo wing the decay of known short-lived isomers. The region of known isoto pes is extended to the predicted proton drip line for indium and silve r, and beyond it for antimony and rhodium.
