Abstract
Detailed study of Rf and No isotopes radioactive decay properties
Highlights
Improvement in the experimental methods and carrying out experimental investigation with the latest developments in the detection system area are one of Eurasian Journal of Physics and Functional Materials, Vol.3(4)the main objectives in modern nuclear physics of superheavy and heavy elements synthesis
In the experiments of 256 Rf the spontaneous fission fragments (SF) properties studying at the SHELS separator with using neutron detector consists of 543 He-counters, could not be observe a single event of α -decay, corresponding to 256 Rf
Decay properties of 256 Rf were refined in investigating the complete fusion reaction 50 Ti+ 208 Pb → 256 Rf ∗

Sokol1, A. Lopez-Martens4, K. Hauschild4, O. Dorvaux5, B. Gall5, P. Mosat6, B.S. Sailaubekov1,2,3 The experiments of detailed study of No and Rf isotopes radioactive decay properties in complete fusion reactions 50 Ti+ 208 Pb and 48 Ca+ 208,206,204 Pb with subsequent neutron evaporation from the excited compound nucleus at the kinematic separator SHELS were performed in FLNR JINR. The data of the 256 Rf decay properties and preliminary data of 250 No decay properties are presented. Keywords: No and Rf isotopes, radioactive decay, complete fusion reactions, excited compound nucleus.
