Elastic and inelastic scattering of <sup>15</sup>N ions by <sup>9</sup>Be at 84 MeV
2016, Nuclear Physics ACitation Excerpt :Early work to put heavy-ion elastic scattering potentials on a more fundamental level by the use of semi-microscopic double folding potentials [1] showed, that the majority of the interactions could be well described except for the three nuclei 6Li, 7Li and 9Be. For these three nuclei, the strengths of the calculated real potentials had to be reduced by ∼0.6 [2,3]. Since these three nuclei have relatively low break up energies and strong polarizability, it was considered that these conditions produced the need for this strength reduction.

2007, Progress in Particle and Nuclear PhysicsCitation Excerpt :Coupling to breakup is known to have an important effect on the elastic scattering, particularly for energies near the top of the Coulomb barrier, for a wide range of targets, see e.g. [90]. The first hint of this important effect came when the hitherto highly successful double-folding model potential [119] had to be renormalised by a factor of order 0.5 to fit elastic scattering data for the weakly-bound nuclei 6Li [120], 7Li [121] and 9Be [122]. This renormalisation was subsequently shown to be due to a large positive real DPP produced by coupling to breakup [90,123–125], although the propriety of simulating what is normally a surface-peaked DPP by a simple renormalisation of the whole potential is, to say the least, questionable, particularly if the same potential is to be used to calculate fusion within the one-dimensional barrier penetration formalism.
