• Energy levels of "Tc have been investigated by means of the "Mo(p, my)reaction. Excitation functjons of 7-ray yields were measured with a Ge(Li) detectorin the bombarding energy range froin 2.8 MeV to 5.1 MeV in steps of 10 keVto 100 keV. The decay scheme which includes 40 levels and 104 7 rays has beenconstructred from the comparisons of the lst 2" and the 2nd 4" isobaric analogueresonance yields, threshold energies for 88 )' rays, branching ratios, 7-ray angulardistributions and systematics. Spin and parity values for the 9th, 13th and 15thexcited states were assigned as 1/2", 9/2- and 7/2=, respectively. New levels at1837.5 keV(7/2", 9/2"), 1873.9 keV(7/2", 9/2"), 1888.8 keV(5/2=) amxd 2118.1 keV(7/2", 9/2") were also proposed. A rotation-particle-coupling model calculationhas been undertaken in """"To isotopes. The calculation gives reasonableagreements with the experimental results. . .
