Study of the two-proton halo nucleus 17Ne

Abstract

The (17Ne) nucleus is described as two protons outside of a deformed core. The Micro scopic Cluster Model (MCM) is used to describe the three-body system 15O+ p +p 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 17Ne is a two-proton halo nucleus. In the calculations, the energy states (0d5/2), (1s1/2), (0d3/2) and (0f7/2) 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 17Ne.
