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.

In this contribution, we report on results of recent experiments performed at the velocity filter SHIP at GSI in Darmstadt obtained for nuclei above fermium (Z = 100). In particular, new results are presented from an α-decay study of 259Sg. These data resulted in the observation of new isomeric state in 259Sg and in the improvement of the quasiparticle systematics for N = 153 isotones. [ABSTRACT FROM AUTHOR]

This contribution reviews the recent results of the experiments performed at SHIP in the field of K-isomer studies, where we aimed at a study of high K-structures in odd-mass nuclei. In particular the results from the study of multi-quasi-particle isomeric states in 253No and 255Lr will be presented in detail. The high K-isomer in 253No gives also the possibility to observe a rotational band, which was not observed in previous in-beam studies. [ABSTRACT FROM AUTHOR]

The isotope 261Sg was produced in nuclear reaction 208Pb(54Cr,n)261Sg at velocity filter SHIP in GSI Darmstadt. Its decay products 257Rf and 253No were studied by means of α, α-γ and/or α-X-ray spectroscopy. Improved spectroscopic data for these isotopes is presented as well as new information concerning Jπ values of Nilsson single neutron orbitals in heaviest members of N = 151, 153 and 155 isotonic chains.

This contribution reviews the results of the recent experiments at the velocity filter SHIP in GSI Darmstadt obtained in the region of neutron deficient isotopes from lead to radon. The data for new very neutrondeficient isotopes 187Po, 193,194Rn and their decay properties are presented. The isotopes were produced and identified in the complete fusion reactions 46Ti+144 Sm→187Po+3n and 52Cr+144Sm→194,193 Rn+2,3n. [ABSTRACT FROM AUTHOR]
