Abstract: | The cross sections for the production of nuclides of element 108 via
hot fusion evaporation reactions are studied using a two-parameter
Smoluchowski equation. The optimal reactions for the synthesis of
new nuclides of element 108 with mass numbers from 266 to 271 are
suggested. The macroscopic-microscopic approach predicts a strong
deformed shell closure at Z \approx 108 and N=162. The synthesis
of more nuclides of element 108 is meaningful to the confirmation of
the existence of this deformed shell closure. |
