dc.description.abstractThe relativistic projectile fragmentation of a 750 MeV per nucleon beam of Ag107 was used to populate isomeric states in neutron-deficient nuclei around A=80-90. Reaction products were separated and unambiguously identified using the GSI FRagment Separator (FRS) and its ancillary detectors. At the final focal plane, the fragments were slowed from relativistic energies by means of an aluminium degrader and implanted in a passive stopper in the center of the high-efficiency, high-granularity Stopped Rare Isotope Spectroscopic INvestigation at GSI (RISING) germanium array. This allowed the identification of excited states in the N=Z nuclei 4386Tc and, for the first time, 4182Nb. Isomeric states have also been identified for the first time in Tc87,88, and a previously unreported isomer was observed in Nb84. Experimental results are presented along with a discussion on the structure of these nuclei based on interpretations provided by several theoretical models. © 2009 The American Physical Society.-
