Identification Of The Gamma-Transitions And Possible 7/2[413] Bands In Tc105-109 Isotopes

Several gamma transitions in Tc105-109 nuclei were identified for the first time from the spontaneous fission studies with a Cf-252 source and the Gammasphere. New level schemes are here proposed. The bands with the large signature splitting in Tc-105,Tc-107 are evidently derived from g(9/2) orbitals. These bands are compared with the analogous bands in Rh-103,Ag-103, and Y-99.
