An idea for predicting the evaporation residue cross section in superheavy mass region

A trial to clarify the main contributors to the evaporation residue cross section in the superheavy mass region is presented. The precise analysis of these factors enables us to understand more clearly the trend of experimental data decreasing exponentially when the atomic number of the residue nucleus increases. It is found that almost all of the experimental data producing nuclei with Z=104 to 114 are fitted with a common parameter set within a reasonable allowance, i.e., ±0.7 order. In this sense, this model has a reliable predictability for the synthesis of new elements.
