Synthesis of New Nuclei and Study of Nuclear Properties
and Heavy-Ion Reaction Mechanisms

Leader:   Yu.Ts. Oganessian

Scientific Programme:
Te experiments with 233U, 237Np, 243Am and 249Cf targets to synthesize SHE of Z=112, 113, 115, 118 close to the region of predicted spherical shells. Mass determination of superheavy nuclei produced in reactions with 48Ca. Synthesis and chemical izolation of heavy elements Z=104, 112 and 114 by the solution and gaschromatography chemistry methods. Investigation of the dynamics of spontaneous and induced fission and of the cluster decay. Study of the mechanism of nuclear interaction and of the decay of heavy hot compound nuclei. Investigation of nuclei close to the nucleon stability boundary. Study of nuclear reactions using radioactive nuclei beams.

Expected main results in 2004:
