The level scheme of 99Tc was studied by y-ray spectroscopy with the 96Zr(6Li, 3 n y)99Tc reaction. New levels were established and spins and parities assigned. 99Tc is compared with 93'95'97Tc, with the neighbouring even-even Mo-isotopes and with the results of an IBFM calculation.Nuclear Reaction: 96Zr(6Li, 3n)99Tc, ELi=24-31 MeV, measured E~, I~, y-excitation functions, yy-coincidences, y-angular distributions, 99Tc deduced levels, J, re, enriched target, Ge(Li). IBFM calculation.
