“…This was confirmed by the coupled-channel tests performed in [143]. In figure 15 the transfer to the The transfer cross section for 10 B( 7 Be, 8 B) 9 Be at 84 MeV: grey lines are the result of DWBA calculations whereas black lines are those for CCBA. three first states in 9 Be is predicted.…”

“…The MST approach, however, surpasses such mean field expansions since it takes into account structure features of the projectiles beyond the total matter density distribution alone. It has been applied to proton elastic scattering from 11 Li, in inverse kinematics, and shows a much better agreement with data than the KMT optical model approach due to its inclusion of both recoil effects (of the 9 Li core) and breakup effects of the halo neutrons [62].…”

The differences between the grey lines and the black lines give an estimate of the error made when using the one-step approach.…”

“…A number of experimental reviews on the physics of light exotic nuclei [1][2][3] have focused mainly on experimental techniques and the physics that could be extracted from those measurements. Any attention paid to the reaction models used in the analyses was rather modest, and has appeared mainly in conference proceedings [4][5][6][7][8], or published summer school lectures [9]. Our aim in this topical review is to fill this gap by assessing the progress in the theory of modelling reactions with light dripline nuclei.…”

We review here theoretical models for describing various types of reactions involving light nuclei on the driplines. Structure features to be extracted from the analysis of such reaction data, as well as those that need to be incorporated in the reaction models for an adequate description of the processes, are also under focus. The major unsolved theoretical issues are discussed, along with some suggestions for future directions of the field. 7 1

Improved implementation of the transfer-to-the-continuum method for single-neutron knockout reactions and the validity of standard approximations

Approximations made in implementing the transfer-to-the-continuum model for single-nucleon knockout reactions on light target nuclei are investigated using more complete numerical calculations. The reliability of different proposed approximation schemes and their predicted cross sections are discussed. The results of the model calculations that use realistic descriptions of the distorting interactions entering the theory are also compared with available experimental data for reactions induced by 15 C and 34 Si secondary beams. These transitions, with different neutron orbital angular momenta, also have significantly different values of the neutron separation energy. The different approximation schemes are shown to agree most closely for the weakly bound and spatially extended, l = 0, 15 C ground state transition. For an l = 2 transition in 34 Si, the approximation schemes are shown to be dependent on the nucleon separation energy. In all cases comparisons of even the most accurate implementation of the theory with the experimental data reveals deviations in both the magnitudes of the predicted integrated cross sections and their momentum distributions. Furthermore, the use of the different approximation schemes also produce quite significant effects on the shapes of the predicted momentum distributions and the integrated partial cross sections.
