Investigations of very neutron-deficient isotopes below100Sn in40Ca-induced reactions

  • Published:
Zeitschrift für Physik A Atoms and Nuclei

Abstract

Very neutron-deficient isotopes of rhodium, palladium, silver, cadmium and indium in theN=50 region were studied at the GSI on-line mass separator following bombardment of58, 60, 62Ni and63, 65Cu targets with 4.0 MeV/u ions of40Ca. The known properties of the β-delayed proton precursor95mPd were confirmed, but a search for direct proton decay of95mAg was not successful. Beta-delayed proton activities observed at mass-numbers 94, 96, 97 and 100 were assigned to the precursors94Rh(66±14 s),96Ag(5.1±0.4s),97Cd(3 +4−2 s) and100In. In addition,94Pd(9.0±0.5 s) was identified from β-γ-X studies. Individual decay schemes of95m96Pd and96, 98Ag are reported.
