High-spin states in 94Tc

Abstract High-spin states in 94 Tc have been populated through the 93 Nb(α, 3n) reaction. Excitation functions, γ-ray angular distributions, γγ coincidences and half-lives were measured. New levels, with the following energies (in keV), spins and parities are proposed: 1373.5, 9 + ; 1447.3, (8 + ); 2064.0, (11 + ); 2066.2, (9 − ); 2234.9, (10 − ); 2346.7, (13 + ); 2420.7, (11 − ); 3454.1, (13 − ); and 4059.3, (15 − ). The existence of an isomer with 50 ns 1 2 was established at an energy equal to or greater than 2420.7 keV.
