Towards the Studies of Proton Ground-state Radioactivities Below 100Sn

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 100Sn. 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 I=4 proton emitters 93Ag and 89Rh are identified as primary candidates to be discovered
