Low-lying levels of 96 Tc excited in the 93 Nb(α, n) 96 Tc reaction

The level structure of96Tc has been investigated by means of the93Nb(α, n)96Tc reaction. Excitation functions have been measured for some γ-transitions in the energy intervalEα=(11÷14) MeV. Gammagamma coincidence measurements have been made with two germanium detectors atEα=10.8 and 14.0 MeV. A new low-lying level at 49.1 keV withJ=6 and a mean life <3 ns has been identified. Eighteen new levels at 482.3, 506.6, 529.7, 541.2, 550.9, 575.0, 580.8, 618.8, 646.1, 731.8, 752.4, 787.9, 815.0, 866.2, 886.1, 947.1, 977.7 and 1062.6 keV have been also observed. Moreover, with the reaction96Mo(p, nγ)96Tc and a pulsed beam, the mean life of the 120.2 keV level has been determined asτ m =(36.4±0.6) ns.
