Anomalous large-angle $\alpha$-scattering in a single-folding model with microscopic densities

A. -G. Serban, F. Salvat-Pujol, N. Sandulescu, P. Marevi\'c

A single-folding model with microscopic mean-field densities reproduces anomalous large-angle alpha scattering in sd-shell N=Z nuclei using a unified parameter set where only two terms vary with mass number.

Claims

C1strongest claim

Our results show that ALAS in sd-shell nuclei is reasonably well reproduced using the microscopic densities together with an α-nucleon interaction characterized by a unified parameter set, in which only two parameters vary with the mass number.

C2weakest assumption

The assumption that the Gaussian-form α-nucleon interaction with energy dependence and range constrained by previous theoretical studies, when folded with mean-field densities, accurately captures the physics of ALAS without additional adjustments beyond the two mass-dependent parameters.

C3one line summary

A single-folding model with microscopic densities and a nearly unified alpha-nucleon interaction reproduces anomalous large-angle alpha scattering in sd-shell N=Z nuclei.
