“…This procedure we have adopted in Ref. [23] where, the average of all these SFs obtained in different intervals gives the final SF of a given state. This also brings additional uncertainties in the extracted SFs along with the existing uncertainties due to the optical potentials, which are around 46% and 33% (see Ref.…”

“…As a first step in this direction, in Refs. [22,23] we have applied the combined R-matrix [24,25] and the Lagrange mesh [26] methods, to the transfer reaction study in the DWBA frame work. Apart from simplifying the calculations, usage of these methods lead to fast and accurate numerical computations.…”

“…This paper is a short review of our work on transfer reactions, where apart from the utility of the R-matrix and the Lagrange mesh methods, I also discuss about the sensitivity of the transfer cross sections to the bound state wave functions [23]. For this, a supersymmetric bound state partner of the Woods-Saxon potential is used, which gives a different wave function in the nuclear interior but have the same asymptotics.…”

We have recently applied the R-matrix method to transfer reactions in the distorted wave Born approximation (DWBA) framework. In our approach the wave function in the internal region is expanded in terms of Lagrange basis, which provides a fast and efficient way to compute the matrix elements. This paper is a short review of our work on transfer reactions. I discuss applications of our approach by considering the 16 O(d, n) 17 F and 12 C( 7 Li, t) 16 O reactions, which are specific examples of neutron and α transfer, respectively. In particular, I discuss the role of the remnant terms, post-prior form equivalence, peripherality of the reaction and sensitivity of the transfer cross sections to the bound state wave functions. Effects of the remnant terms and of the supersymmetric bound state potentials on the extracted spectroscopic factors are also discussed.

Nuclear reaction study is important to understand elemental abundance in the universe and stability of stars. For several reactions due to the paucity of experimental data or diffculties in performing the direct measurements, we depend upon theoretical estimates and therefore one needs reliable theoretical models with minimum inputs. This paper is a short review of our work on nuclear reactions and their applications to astrophysics. In particular, we discuss the nuclear transfer and breakup reaction while focusing on our theoretical modelings and techniques involved.
