| contents | We investigate anomalous large-angle scattering (ALAS) of $α$-particles from $N=Z$ nuclei within the framework of the single-folding model. Differential cross sections are calculated by folding the $α$-nucleon interaction with nuclear density distributions obtained from both relativistic and non-relativistic mean-field models. The folding procedure employs a Gaussian-form $α$-nucleon interaction, with its energy dependence and range constrained by previous theoretical studies. 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. |
