Abstract
This work explores the investigation of medium-energy angular distribution literature data for p + 12C elastic scattering. The goal is to highlight the possible existence of α-cluster structures in the ground state of the carbon nucleus; this matter is approached via Coupled-Channel (CC) calculations, which describe the 12C nucleus through a classic spheroidal-like structure, along with a further contribution, which explicitly takes into account the possible existence of a triangular α-cluster structure for the nucleus, treated similarly to the X-ray diffraction by molecules. The results point towards a rather small cluster component in the ground state of the carbon nucleus: an upper limit of ≃ 1% is shown with a 99.75% confidence level and an inter-cluster distance of ≃ 3.9fm, compared, in the end, with various theoretical predictions reported in the literature.
