Description
Using a dynamical model, I would like to discuss the possibility of
synthesizing new superheavy elements. As a dynamical model, we employ
Langevin equations based on the fluctuation-dissipation theorem. In order to synthesize the double magic superheavy nucleus, like as 298Fl, we must generate more neutron-rich compound nuclei (for example 304Fl) because of the neutron emissions from excited compound nuclei. Such neutron rich compound nucleus has advantages to achieving a high survival probability, comparison with 292Fl and 298Fl. In the seminar, I would like to explain this mechanism of decay process, and also discuss the way to produce suchneutron rich compound nuclei.
