Description

We perform a detailed analysis for the structure of 31F, which is a candidate of the halo nucleus. We calculate the radius and total reaction cross section using a three-body wave function of 29F+n+n and discuss how the competition between the neutron-pairing and the single-particle energy induces structural changes of 31F. The present analysis further clarifies a new aspect of the anti-halo effect that suppresses the halo structure in the ground state. (author)
