Background: Nuclear transfer reactions are a useful tool to study the structure of a nucleus. For reactions involving weekly bound nuclei, breakup effects can play significant role and theoretical calculations can be computational expensive in such cases.
Purpose: To utilize the Lagrange-mesh and R-matrix methods for nuclear transfer reactions.
Methods: We use the adiabatic distorted wave approximation (ADWA) method which can approximately treats the breakup effects in a simpler manner. In our approach, we apply the R-matrix method combining it with the Lagrange-mesh method, which is known to provide the fast and accurate computations.
Results: As a test case, we calculate the angular distribution of the cross sections for the 54Fe(d,p)55Fe reaction, where deuteron breakup effects play important role.
Conclusions: We show that these methods work well in the ADWA framework, and we look forward to applying these methods in coupled channel calculations.
