Erratum: Continuum-discretized coupled-channels analysis of6Li→+4He

Abstract

On page 1899, just below Eq. ͑4͒, the component T R (d) of the 6 Li-4 He second-rank tensor potential, coming from the deuteron-4 He tensor interaction was wrongly named the deuteron-target tensor potential. Equation ͑5͒ and the two sentences preceding it refer to the d-4 He second-rank tensor potential T R d-4 He (d) and T R (d) in this equation and these lines should be replaced by T R d-4 He (d). The component T R (d) was derived from this deuteron tensor potential using a cluster-folding model of 6 Li and T R (d), shown by the dashed curve in Fig. 6. The results and conclusions as presented in the paper remain unchanged.

Determination of 6Li4He interaction from multi-energy scattering data

“…Conventionally parameterised potentials fail seriously, even when the absorption is allowed to be l-dependent. The inclusion of cluster transfer processes within the higher order DWBA framework [2] and the inclusion of coupling to projectile excitations [4], while clearly important, still do not result in satisfactory fits. In any case, the natural conclusion is still that the detailed description of nuclear scattering in terms of a potential model is not possible with 6 Li -4 He scattering.…”

“…Various studies of the scattering of unpolarised [1] and polarised [2,3,4] 6 Li from 4 He using conventional potential models have failed to yield a fully satisfactory description of the data. Conventionally parameterised potentials fail seriously, even when the absorption is allowed to be l-dependent.…”

“…Majorana terms are generally absent in published potential models of 6 Li - 4 He scattering. In a microscopic picture such as RGM these would arise, for example, from cluster exchange terms.…”

“…In the present paper we apply a recently developed technique, fulfilling the above requirements, to analyse 6 Li elastic scattering from 4 He. We have available numerical data for the following CM energies: 2.2 MeV and 7.85 MeV [3]; 11.1 MeV and 15.0 MeV [2].…”

“…For brevity, we shall refer below to this method for observable to potential inversion as the 'Generalised Iterative Perturbative', GIP, method. For recent applications to d + 4 He scattering, including the determination of phase shifts, refer to Refs [8,9,14].…”
