The level structure and the decay properties of levels in /sup 97/Tc up to 2208 keV excitation have been investigated via measurements of excitation functions of singles ..gamma.. rays and via ..gamma gamma..-coincidence experiments following the /sup 97/Mo(p,n..gamma..) reaction with proton energies between 1.5 and 8.0 MeV. From these experiments and from high resolution singles energy and directional-correlation measurements an extended scheme has been obtained which includes 69 levels of which about 40 are new. The directional correlations provided unique J/sup (/ assignments for 14 levels, limits for a few others, and multipole mixing ratios for several electromagnetic transitions. The results are compared with unified model calculations.
