Thermodynamic temperature and level density of SHN

Nuclear reaction rates are the quantities of fundamental importance in Nuclear Astrophysics. The use of theoretical predictions is still required for the estimation of experimentally unknown values. Hence extrapolation is the mathematical tool to use for further prediction like thermonuclear reactions and heavy ion fusions either by cold or hot fusion process in r-, p- and rp- processes of nuclear synthesis, of fused compound systems of high N/Z ratio, which are capable to overcome the Coulomb repulsion and hence form short lived super heavy nuclei. A total of 666 nuclides from Z=104 to Z=140 are studied using the statistical model code developed by our group, for excitation energy and level density. Fixing of these 666 nuclides is according to the shape of the isotopes, nearly spherical. In synthesising these isotopes, new procedures may be followed than the currently adopted procedures for elements upto Z=118
