Abstract
The DCM, based upon QMFT, is used to study hitherto unexplored characteristics of superheavy nuclei ranging from Z=108-117. The deformations and orientations of the incoming and out-going nuclei/ fragments are included within this formalism which play extremely important role for the superheavy mass region.
The model considers all the decay products of a CN as dynamical mass motions of preformed fragments or clusters through the interaction barrier, thereby including structure effects of the CN explicitly. The shell effects, which play vital role in the formation and decay of superheavy nuclei, are also explored within this framework by assigning Z=126 and 120 with N=184, respectively, as the best suited magic pairs for addressing ER and ff processes. For a given CN at a fixed E*CN, the only parameter of the model, the neck length parameter ∆R, is found to be independent of incoming reaction partners.
In addition to this, role of the barrier modification which is an inbuilt property of DCM is analyzed for various heavy ion reactions leading to superheavy nuclei. Finally, the isospin effects of changing the N/Z ratio of Z=115 compound nucleus have also been investigated.
