Abstract
Transfer reactions like A X(d,p) A+1 X are a powerful tool to investigate nuclear structure properties (see e.g. [1–3]) and the emergence of radioactive beams with high intensity will allow the use of this kind of reactions to study the properties of exotic nuclei. Nevertheless the analysis of reactions involving deuteron remains a difficult task because of its weakly bound and composite features. To overcome these issues, R.C. Johnson et al [4] and G.H. Ratwitcher [5] proposed in the seventies the Continuum Discretized Coupled Channels (CDCC) formalism which explicitly takes into account the composite property of the deuteron and includes the effects on cross sections of the coupling between the breakup and the deuteron ground state channels. Since then the CDCC approach has been widely studied [6–8] and it has been quite successfully applied to analyse elastic [7–9] , inelastic [8,10] and transfer cross sections [11–13]. In this contribution, I will propose to re-analyse transfer reactions by the means of CDCC+adiabatic approach for a set of targets with N = 20 or N ≈ 28. I will show that with this approach, using both the differential cross sections and the vector analysing powers one can determine the orbital angular momentum and the spin of the captured nucleon without any adjustment.
Highlights
Deuteron induced reactions can be useful to produce radioisotopes of medical interest, to study materials and to investigate nuclei structure especially by means of transfer reactions. These transfer reactions are usually interpreted by using DWBA approach involving global optical potentials for deuteron
We propose here to use the Continuum Discretized Coupled Channels (CDCC) approach and the DWBA approach to interpret the transfer cross sections and the vector analysing power allowing us to get complete information of the captured nucleon without introducing any adjustment even if it is well known that the CDCC description of the elastic cross section remains to be improved at low incident energies
Transfer reactions like (d,p) have been widely used in the past to investigate the properties of nuclei and appear to be a promishing tool to discover the properties of exotic nuclei by means of inverse kinematics and by using high intensity radioactive beams
Summary
Deuteron induced reactions can be useful to produce radioisotopes of medical interest, to study materials and to investigate nuclei structure especially by means of transfer reactions. In spite of its success to analyse the experimental data, it requires to adjust the optical potential parameters of the entrance channel in order to reproduce the elastic cross sections which means that both the transfer cross sections and the elastic one have been measured. These data are not always available simultaneously.
