High-spin Shell-model States in the Isotope 90Tc
High spin states in the nucleus Tc-90 have been identified for the first time via the fusion evaporation reaction (Ni(Ar,3pn)Tc)-Ni-58-Ar-36-Tc-90, at 149 MeV beam energy. The OSIRIS spectrometer with an additional high purity Ge detector at 162-degrees and several particle detectors were used to measure gammagamma and particle-gammagamma coincidences, directional correlations of oriented states (
