    Belgium, Bulgaria, CERN, China, Czech Republic, Finland, France, Germany, Egypt, India, Italy, Japan, Kazakhstan, Mongolia, Poland, Romania, Russia, Slovakia, South Africa, Spain, Switzerland, Sweden, Ukraine, United Kingdom, USA. Scientific Programme:
    Synthesis and investigation of the properties of nuclei at stability limits. Investigation of the mechanisms of heavy-ion-induced reactions. Study of physical and chemical properties of heavy and superheavy elements.

    Expected main results in 2016:

    • Conducting experiments on synthesis of new isotopes of element 118 as well as neutron-deficient isotopes of Fl and element 115 in reactions with 48Ca ions.

    • Preparation of the experiment aimed at detailed spectroscopy of the decay properties of the 288115 isotope and its daughter products, using the modernized separator VASSILISSA (SHELS) +GABRIELA. Conducting model experiments to study the decay properties of the Rf and Db isotopes.

    • Preparation and conduct of experiments to study the chemical properties of element 113.

    • Data acquisition during mass measurement of the 283Cn isotope produced as a daughter product in the 48Ca + 242 Pu reaction using the modernized mass separation system of the MASHA setup. Data acquisition on the mechanisms of complete fusion and multinucleon transfer reactions for nuclei close to the neutron shell closure N = 126 using mass-spectroscopic methods.

    • Production and study of the properties of new neutron-rich heavy and super heavy nuclei in binary multinucleon transfer processes and quasi-fission. Data acquisition on the properties of nuclei at nucleon driplines. Study of multicluster decay of heavy and superheavy nuclei. Development of physical setups.

    • Investigation of the structure of the exotic nuclei 5H, 10Li, 17Ne, and 27S using radioactive beams.

    • Study of the properties of nuclear reactions with loosely bound cluster nuclei over a broad range of energies (5-25 A MeV). Measurement of individual reaction channel cross-sections leading to the formation of new nuclei at the drip-line. Manufacture of detectors for the high-resolution magnetic analyzer MAVR aimed to register nuclear reaction products.

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

    • Development of the knowledge base on nuclear physics accessible through the Internet.

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