Abstract:	Low-lying states in ⁹⁶Tc excited through the ⁹⁶Mo(d, 2nγ) reaction have been investigated by means of on-line internal conversion electron and γ-ray spectroscopy. Measured singles spectra and relative excitation functions together with particle-γ and γ-γ coincidences were used to identify and fit the transitions in a level scheme. The low-lying positive-parity states 2⁺–7⁺and negative-parity states 2^? and 3^? are compared with those appearing systematically in doubly odd ^{94, 98}Tc and ^92–96Nb isotopes. Comparison is also made with simple shell-model calculations for those nuclei based on the $π(p_{12}, g_{92})^{p_{ν}} (d_{52})^{n}$ configuration space and the tendency of the multiplet structure of the wave functions is discussed.
