Average resonance spectroscopy in 93, 95, 97Tc

The (p, γ) reactions on the ⁹²Mo, ⁹⁴Mo and ⁹⁶Mo isotopes were studied in the energy range E_p = 2.4–3.0 MeV using a Ge(Li) detector incorporated into a three-crystal pair spectrometer and a Ge(Li) detector in coincidence with a NaI(Tl) detector. A three-crystal pair spectrometer was utilized to determine the average yield of γ-rays leading directly to the low-lying states in each of the three residual nuclei. These average yields were examined for a possible correlation between the intensity of high-energy γ-ray transitions and the J^π of the final state. The data indicate that such a correlation exists. A two-dimensional coincidence experiment determined the decay scheme of the low-lying excited states in ⁹³Tc ⁹⁵Tc and ⁹⁷Tc. The J^π assignments inferred from these experiments are consistent with those for the states in ⁹³Tc, ⁹⁵Tc and ⁹⁷Tc which have previously been obtained. For those states which were previously unassigned, the results of this experiment are as follows (all energies are in keV): . The state at 2429 keV in ⁹³Tc has not been reported previously.
