Application of KANTBP 3.1 Program for Studying Nuclear Reactions

A modified version of the KANTBP 3.1 program is presented. It implements a stable high-order finite element method for solving a multichannel scattering problem for a system of second-order ordinary differential equations with complex-valued potential matrices. The benchmark calculations of fusion and quasi-elastic cross sections for nuclear reactions ¹⁶O + ⁴⁴Ca and ⁴⁸Ca + ²⁴⁸Cm are provided. A comparison with the outputs of the well-known R-matrix and CCFULL-sc programs is reported.
