Description
Important quantities that input to one-nucleon transfer reactions are one-nucleon overlap functions. Usually, they are modelled by single-particle wave functions that are solutions of one homogeneous Schrodinger equation with some "standard" Wood-Saxon potential. However, they must come from solution of a Schrodinger-like inhomogeneous equation with the source term that contains information about interaction of the removed nucleon with the rest. In the source term approach, the spectroscopic factors are not the same as those given by widely used shell model codes. They follow the highly-discussed trend observed in one-nucleon removal reaction that reveals reduction of spectroscopic strengths in nuclei. Another advantage of the source term approach is that it automatically guarantees the correct asymptotic behaviour of the overlap functions, which is very important for applications in nuclear astrophysics. Examples of application of the method will be given and discussed.
