EXPECTATIONS AND LIMITS TO SYNTHESIZE NUCLEI WITH Z ≥ 120
Annotatsiya
In order to explore the possibilities to synthesize the new superheavy elements with Z =120, 122, 124, 126 some hot-fusion (mass asymmetric) reactions and cold-fusion (less mass asymmetric) reactions are studied. The dynamics of reaction with massive nuclei and the formation probability of heavy and superheavy elements with Z =90-126 in the asymmetric and symmetric reactions are discussed. The systematics of fusion probability P CN and evaporation residue cross section σ ER in these reactions are presented. Moreover, we explore the possibility of synthesis of superheavy nuclei by the use of reaction with the neutron rich radioactive beam 132 Sn , and by symmetric reactions like 136 Xe + 136 Xe and 139,149 La + 139,149 La .
