We propose a correction method to non-resonant process in the R-matrix theory by adding theoretical backgrounds which is independent on the incident particles. This method is validated through a simultaneous analysis for the ⁶Li(p,p₀) ⁶Li, ⁶Li(p, a₀)³He, ³He(a,a₀) ³He and ³He(a,p₀) ⁶Li reaction cross-sections. We also discuss about physical backgrounds of the present approach.
