Description
Search for the new elements has been one of the major area of research activity in physics and
chemistry over last few decades. Elements up to 294Og (atomic number Z = 118) have been synthesized
successfully using fusion evaporation route, where either double magic nuclei 208Pb (in the synthesis
of Z = 104 -113) or 48Ca (Z = 114 - 118) were extensively used due to extra stability achieved from their
spherical shell structure. But for the synthesis of elements beyond Z = 118, 48Ca beam can no longer
be used as in that case the other reaction partner required would be highly radioactive and currently
impossible to produce in sufficient quantities.
So it is extremely important to understand the reaction dynamics and its dependence on entrance
channel parameters like shell structure, isospin asymmetry and ground state deformation of the
reaction partners. A systematic study has been performed at the Australian National University using
other possible beams 50Ti, 54Cr along with 48Ca to understand the reaction dynamics which will be
presented during the talk.
