Isomeric States In (255)Rf, (256)Rf And (257)Rf

In this work, we present results from the investigations of high-K isomers in (255)Rf, (256)Rf and (257)Rf isotopes produced in Ti-50+Pb-207 and Ti-50+Pb-208 reactions. The method of time and position correlation search was used to identify ER-CE-alpha/SF events in the data. Previously known high-K states in (256)Rf and (257)Rf were confirmed. A search for high-K isomer in (255)Rf was performed for the first time. Observation of ER-CE correlations with a lifetime of approximate to 30 mu s indicates the presence of isomeric states also in this isotope.
