Investigation of the nuclear structure of technetium-93 utilizing the (helium-3,proton-neutron-gamma) reaction
Abstract
The nuclear structure of 93Tc was studied using the 92Mo(3He,pnγ) reaction, which has populated most states in the nucleus below 2 MeV excitation energy. The experiments included the gamma ray excitation function, gamma ray angular distribution and gamma-gamma coincidence. The results were compared to the shell model calculations produced by the computer software OXBASH[36] with the N50J residual interaction and a 78Ni core. All theoretical states below 2 MeV were observed and had good energy agreement. Gamma ray branching ratios were in good agreement as well. Although forbidden by the model space, several E1 gamma ray transitions were observed, suggesting collective effects are contributing to the nuclear excitation.
