Big Deformation in 17C

TL;DR

This paper reanalyzes the reaction cross sections of 17C using a modified Glauber model, revealing a large deformation and potential halo structure with a dominant d-wave valence neutron.

Contribution

It introduces a deformed Woods-Saxon density model to analyze 17C, highlighting its large deformation and halo characteristics as a novel insight.

Findings

17C exhibits a large deformation structure.

Evidence suggests a possible one-neutron halo in 17C.

Valence neutron predominantly occupies a d-wave state.

Abstract

Reaction- and interaction cross sections of 17C on a carbon target have been reanalyzed by use of the modified Glauber model. The analysis with a deformed Woods-Saxon density/potential suggests a big deformation structure for 17C. The existence of a tail in the density distribution supports its possibility of being a one-neutron halo structure. Under a deformed core plus single-particle assumption, analysis shows a dominant d-wave of the valence neutron in 17C. Key words Cross section, Glauber model, Density distribution, Halo, Deformation.
