We have applied the Gamow shell model to calculate nuclear observables of ^26-31Ne isotopes pertaining to one-neutron halo structure, these nuclei being situated close to neutron drip-line. As both many-body correlations and continuum coupling are taken into account in that approach, halo structure can be analyzed properly. Our calculations provide good descriptions of ^26-31Ne, where asymptotic behavior is crucial for that matter. One-body density, neutron root-mean-square radii of ^26-31Ne,

... d one-neutron overlap functions of ^29,31Ne have been calculated as well. Our results support the presence of a one-neutron p-wave halo in ^31Ne, already pointed out experimentally. A similar situation also occurs in the ground state of ^29Ne, which is mainly a p-wave valence neutron coupled to the inner ^28Ne core. The 3/2^+ excited state of ^29Ne, which is dominated by a d-wave valence neutron, has also been considered. A larger radius and more extended wave function occur for the ground state of ^29Ne when compared to its 3/2^+ first excited state. The present results suggest that ^29Ne is a good candidate for one-neutron p-wave halo in the medium-mass region.
