  "abstract": "The possibility of the appearance of the clustering structure in the surface is one of the key features determining the nuclear structural properties. In this work, we study the ground-state structure of $^{28}\\text{Si}$ using the antisymmetrized quasicluster model (AQCM), focusing on the deposition of the $α$ cluster structure on the surface. Three candidate structural configurations constrained to reproduce the experimental charge radius are investigated based on the $\\text{SU}(3)$ shell model, the $j$-$j$ coupling shell model, and a localized $7α$ cluster model. Using Glauber-model calculations for intermediate-energy proton elastic scattering, we demonstrate that the angular distribution at and beyond the first diffraction peak is highly sensitive to surface diffuseness, and that the $7α$ cluster model configuration best reproduces the experimental data due to its sharper surface profile. Also, the elastic charge form factors from electron scattering support the existence of the cluster-induced oblately deformed structure.",
