Universal empirical coupled channel calculations for capture cross sections in synthesis of superheavy nuclei

Abstract

A universal empirical coupled channel model, ECC2, is proposed for the systematic description of capture cross sections in heavy-ion fusion reactions. The model combines a modified Broglia--Winther potential, an effective barrier curvature, and a deformation-dependent barrier distribution width. The most probable barrier heights predicted by ECC2 are in good agreement with the extracted values based on measured excitation functions for 367 systems, and the root-mean-square (rms) deviation is 1.39 MeV. ECC2 is applied to 25 fusion reactions ranging from ¹⁶O+¹⁹⁷Au to ⁵⁴Cr+²⁴⁸Cm. The predicted capture excitation functions are consistent with the EBD2.2 predictions for all systems and agree well with the available experimental data.
