The ([Formula: see text]Ne) nucleus is described as two protons outside of a deformed core. The Microscopic Cluster Model (MCM) is used to describe the three-body system [Formula: see text] with Jacobi coordinates. This model strongly exhibits the Coulomb effect and therefore it is used to explore the role of the Coulomb effect in proton halo formation. The main goal of this study is to confirm that [Formula: see text]Ne is a two-proton halo nucleus. In the calculations, the energy states (0[Formula: see text]), (1[Formula: see text]), (0[Formula: see text]) and (0[Formula: see text]) are considered to be occupied by two valence protons. Based on the comparison with other theoretical and experimental studies, the present MCM calculations show that the exotic structure of the valence protons is not evident in the halo structure of [Formula: see text]Ne.
