Theoretical calculations and analysis for n+⁶Li reaction

R-matrix theory is an important theory of light, medium and heavy mass nuclides nuclear reaction in the resonance energy range. FDRR is short for Full and Diagonal Reduced R-matrix. It is a theoretical code, which is based on R-matrix theory and compiled by FORTRAN language. It is developed by the China Nuclear Data Center (CNDC) and Nankai University. Four R-matrix methods have been compiled in FDRR code. They are MLBW and reduced R-matrix method, diagonal energy shift reduced R-matrix method, full R-matrix method, and un-diagonal energy shift reduced R-matrix method. There are 2 input files for FDRR code, FDRRi.dat and FDRRk.dat files. FDRR code can be used for calculating the cross sections, angular distributions, and polarization Data of 2-bodys reactions.
