ISOMERIC STATES IN 255Rf, 256Rf AND 257Rf.

In this work, we present results from the investigations of high-Kisomers in 255Rf, 256Rf and 257Rf isotopes produced in 50Ti+ 207Pb and 50Ti+208Pb reactions. The method of time and position correlation searchwas used to identify ER–CE–α/SF events in the data. Previously knownhigh-Kstates in 256Rf and 257Rf were confirmed. A search for high-Kisomer in 255Rf was performed for the first time. Observation of ER–CEcorrelations with a lifetime of≈30μs indicates the presence of isomericstates also in this isotope.
