With the use of beams from the Holifield Radioactive Ion Beam Facility (HRIBF) at Oak Ridge National Laboratory it should be possible to identify many new isotopes near and beyond the proton drip line. In these investigations, nuclei produced in fusion evaporation reactions will be separated from the incident ions and dispersed in mass/charge with a recoil mass separator and implanted in double-sided Si strip detectors which will be used in conjunction with a gas-filled position sensitive avalanche counter for the study of proton and alpha-particle radioactivity. The present talk will illustrate these possibilities by describing the discovery of Pt, Pb, and Po alpha emitters at the Argonne National Laboratory ATLAS facility with the use of a fragment mass analyzer. It will then focus on experiments looking for new ground-state proton emitters in the mass region between Cs and Tm that will be carried out with the first radioactive beams to become available at HRIBF.
