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 at the Dubna gas-filled recoil separator GFS-2 of the SHE Factory aimed at studying the production cross sections of nuclei in reactions with the ⁴⁸Са, ⁵⁰Ti, and ⁵⁴Cr ions and the decay properties of synthesized nuclei.
Preparation for experiments on the synthesis of elements 119 and 120.
Experiments on the study of the radioactive decay (α-, β-decay, spontaneous fission) properties of short-lived isotopes with Z>100 (No, Rf, Sg) produced in reactions with Ne, Ca, Ti, and Cr ions at the SHELS and GRAND (GFS-3) separators using the GABRIELA and SFiNX detector systems.
Experiments for studying the chemical properties of Cn and Fl at the Superheavy Element Factory.
Development of technologies for manufacturing accelerator targetsfrom 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 set-ups.
Study of nuclei near the boundaries of nucleon stability. Preparation for and the conduct of experiments at the ACCULINNA-2 fragment separator using radioactive beams and the cryogenic targets H₂, D₂, T₂, ³He, and ⁴He.
Experiments at the MAVR set-up aimed at studying reactions with the emission of fast charged particles near the kinematic limit in coincidence with fission fragments. Experiments for studying the structure of neutron-rich nuclei in transfer reactions. Measurements of individual channel cross sections and total cross sections for the reactions with weakly bound nuclei.
Theoretical studies of the mechanisms of heavy-ion-induced reactions.
Maintenance and update of the web knowledge base on nuclear physics.
