Extension of our knowledge of N=Z nuclei up toMo4284are reviewed. Only &ggr;-ray singles data are available forGe64toMo84, so more definitive tests of theoretical predictions of shape coexistence and deformation changes among them are not possible with present data. The limitations of current facilities to probe in the necessary detail the N=Z line and to extend it further are discussed. A new generation recoil mass spectrometer has been designed for HHIRF to overcome present limitations. The key new feature is a momentum achromat in front of a traditional RMS. A proposed radioactive beam facility for HHIRF, along with the new RMS is shown to open up studies of the N=Z line toSn50100and beyond.
