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