Belgium, Bulgaria, CERN, China, Czech Republic, Egypt, Finland, France, Germany, India, Italy, Japan, Kazakhstan, Mongolia, Poland, Republic of Korea, Romania, Russia, Slovakia, South Africa, Spain, Sweden, Switzerland, United Kingdom, USA, Ukraine, Vietnam.

Issues addressed and main goals of research:
Synthesis of nuclei at stability limits and the investigation of their properties. Investigation of the mechanisms of heavy-ion-induced reactions. Study of the physical and chemical properties of heavy and superheavy elements


Expected results in the current year:

  • Experiments on the synthesis of superheavy elements, study of their nuclear and chemical properties in the 48Ca, 50Ti + 243Am, 242Pu, 244Pu reactions at the SHE Factory.

  • Preparation for experiments on the synthesis of elements 119 and 120 in complete fusion reactions with 50Ti ions.

  • Experiments on the study of the decay properties (α-, β-, γ-spectroscopy) of Sg isotopes and heavy isotopes of Rf formed in reactions with 54Cr and 22Ne using the SHELS+GABRIELA separator. Experiments on measuring the multiplicity of prompt neutrons from the spontaneous fission of heavy Rf isotopes in reactions with 22Ne. Test experiment on the spectroscopy of the decay properties of  288Mc isotopes and its daughter products in the 48Ca + 243Am reaction.

  • Formation and decay of double/di-nuclear nuclear system formed in the 86Kr + 232Th, 238U reactions. Study of the mass–energy and angular distribution of fragments produced in these reactions. Investigation of the mechanism of multinucleon transfer. Study of the multi-body decay of low-excited heavy nuclei. Study of the multicluster decay of heavy and superheavy nuclei. Development of physics set-ups.

  • Study of nuclei with Z<20 close to the nucleon drip lines. Analysis of the experimental data on the investigation of the structure of the exotic nuclei 7H, 7,9Не10Li, and 27S synthesized earlier using radioactive beams at the ACCULINNA-2 fragment separator.

  • Experiments at MAVR for studying fast charged particles in coincidence with recoil nuclei. The studies are aimed at determining the reaction mechanism for experiments on the synthesis of new elements. Study of the yield of multinucleon transfer reaction products.  Measurement of total reaction cross sections using low-intensity beams of exotic nuclei.

  • Analysis of experiments conducted at the MASHA set-up aimed at studying the operational stability of a new design of the hot catcher during the separation of short-lived mercury and radon isotopes synthesized in complete fusion reactions. Measurements according to a prescribed methodology at MASHA for studying the influence of chemically inert coatings on the separation efficiency of the hot catcher – ERC ion source for inert gases and mercury system.

  • Theoretical studies of the mechanisms of heavy-ion-induced reactions.

  • Maintenance and update of the web knowledge base on nuclear physics.

  • Investigation of sizes and shapes of exotic nuclei employing laser spectroscopy methods.
