Abstract. A decay spectroscopy experiment was performed within the EURICA campaign at RIKEN in 2012. It aimed at the isomer and particle spectroscopy of excited states and ground states in the mass region below the doubly magic 100 Sn. The N = Z nuclei 98 In, 96 Cd and 94 Ag were of particular interest for the present study. Preliminary results on the neutron deficient nuclei 93 Ag and 94 Ag are presented. In 94 Ag a more precise value for the half-life of the ground state's superallowed Fermi transition was deduced. In addition the energy spectra of the mentioned decay could be reproduced through precise Geant4 simulations of the used active stopper SIMBA. This will enable us to extract Q β values from the measured data. The decay of 93 Ag is discussed based on the observed implantation-decay correlation events.

“…The projectile fragmentation technique offers higher luminosity, due to the higher energy of the beam which enables the use of thick targets, and clear separation of the contaminants via event-byevent tagging. Reported observations of 100 Sn using this method were made in the relativistic energy domain using 1 GeV=nucleon 124 Xe and 112 Sn beams [6,7], as well as in the intermediate energy domain from a 60 MeV=nucleon 112 Sn beam [8]. While in the relativistic energy domain the level of contamination from other species in the secondary beam was acceptable for performing decay spectroscopy [7], this is not the case at lower incident energies.…”

High levels of contamination come from low momentum tails of higher rigidity fragments which extend exponentially and overlap with the momentum acceptance of the fragment separator.…”

The beta-decay properties of the N=Z nuclei 96Cd, 98In, and 100Sn have been studied. These nuclei were produced at the National Superconducting Cyclotron Laboratory by fragmenting a 120 MeV/nucleon 112Sn primary beam on a Be target. The resulting radioactive beam was filtered in the A1900 and the newly commissioned Radio Frequency Fragment Separator to achieve a purity level suitable for decay studies. The observed production cross sections of these nuclei are lower than predicted by factors of 10-30. The half-life of 96Cd, which was the last experimentally unknown waiting point half-life of the astrophysical rp process, is 1.03_{-0.21};{+0.24} s. The implications of the experimental T_{1/2} value of 96Cd on the abundances predicted by rp process calculations and the origin of A=96 isobars such as 96Ru are explored.

“…For ^''Y, two events identified in [39] might indicate that the half-life of this nucleus is longer than 170 ns, hence there is a chance to observe proton emission in a dedicated fragmentation or fusion-evaporation study.…”

Ground-state properties of deformed and transitional proton emitters in the relativistic Hartree-Bogoliubov model AIP Conf.Abstract. The discovery potential for new proton-emitting isotopes of elements with atomic numbers 35 < Z < 47 in a classical implantation-decay experiment is analyzed. In particular, proton separation energies and half-lives as well as the production and detection methods are discussed for nuclei below ^'^''Sn. Fusion-evaporation reactions studied by means of the Recoil Mass Separator at the Holifield Radioactive Ion Beam Facility (HRIBF) at Oak Ridge National Laboratory are compared to heavy-ion fragmentation based studies at the National Superconducting Cyclotron Laboratory using the A1900 separator The 1=4 proton emitters '^Ag and ^^Rh are identified as primary candidates to be discovered.
