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 aimed at the study of complete fusion reactions of actinide target nuclei with 48Са, 50Ti, and 54Cr ions performed at GFS-2 of the Factory of Superheavy Elements (SHE).
- Preparation for the synthesis of elements 119 and 120.
- Experiments aimed at studying the properties of the radioactive decay (α-, β-decay, spontaneous fission properties) of No, Rf, and Sg heavy isotopes formed in reactions with Ne, Ca, Ti, and Cr ions at the SHELS separator using the GABRIELA and SFiNX detecting systems.
- Experiments for studying the chemical properties of Cn and Fl at the Factory of Superheavy Elements.
- Development of a technology for manufacturing accelerator targets from stable and radioactive isotopes, which are stable under long irradiation with high-intensity heavy-ion beams.
- Investigation of mass-energy and angular distributions of fragments produced in multi-nucleon transfer reactions. Study of the multi-body decay of low-excited heavy and superheavy nuclei. Development of physics facilities.
- Investigation of nuclei close the limits of nucleon stability: analysis of experimental data on studying the structure of the exotic nuclei 6,7H, 7,9Не, 8,9,10Li, 27S produced earlier using radioactive beams at the ACCULINNA-2 fragment separator.
- Experiments at MAVR aimed at studying reactions with the emission of fast charged particles near the kinematic limit in coincidence with fission fragments. Measurement of total cross sections for reactions with beams of weakly bound cluster nuclei.
- Preparation for experiments aimed at measuring cross sections of complete fusion reactions using the movable catcher of the U-400 accelerator.
- Theoretical studies of the mechanisms of nuclear reactions with heavy ions.
- Development and update of the web knowledge base on nuclear physics.
