Project of the experimental setup dedicated for gamma and electron spectroscopy of heavy nuclei at FLNR JINR

Important information on the structure of super heavy elements (SHE) can come from the study of lighter deformed transfermium (Z∼100–106) elements. The cross-section for the formation of these nuclei is many orders of magnitude higher than for Z⩾110 so that detailed spectroscopy becomes possible. The advantage of Dubna is the unique possibility to use radioactive actinide targets, which yield higher production cross-sections for heavy elements. The use of actinide targets also makes Dubna a complementary site for heavy element spectroscopy because, until the availability of intense radioactive beams, it is the only way to produce less neutron deficient heavy isotopes. The opportunity to have high intensity (⩾1pμA) accelerated beams with A⩽40 together with the use of exotic targets provide the possibility to study many aspects of heavy ion induced reactions exploiting new generation of high efficiency, high resolution experimental setups. The scientific fields of the application of the new setup could be concentrated on the study of asymmetric combinations leading to excited heavy compound nuclei.
