Cluster scattering in the non-local model

Blog Article

Scattering of weakly bound nuclei with a pronounced cluster structure is strongly affected by their breakup.Usually, this mechanism is accounted for in a three-body model with pairwise potentials.The interaction potentials between complex systems are non-local due to the existence of excitation channels and antisymmetrization.However, a common practice is to use local optical potentials in cluster scattering studies.To assess the validity michael harris sunglasses of replacing non-local optical potentials by their local equivalents, we extend the local-equivalent continuum-discretized coupled-channel (LECDCC) approach proposed by us for deuteron scattering in [Phys.

Rev.C98, 011601(R) (2018)] to the case of cluster scattering.We consider the case of 6Li + 120Sn at 27 and 60 MeV, and compare the angular distributions and reaction cross sections for caruso milk thistle elastic and breakup cross sections with those obtained in the standard continuum-discretized coupled-channel (CDCC) method with local equivalents of non-local potentials.We found that while elastic scattering is not significantly affected by non-locality, the breakup observables could be affected by up to 20% depending on kinematical conditions of their observation.
