Two-Neutron Halo is Unveiled in F 29

We report the measurement of reaction cross sections (σexR) of 27,29F with a carbon target at RIKEN. The unexpectedly large σexR and derived matter radius identify 29F as the heaviest two-neutron Borromean halo to date. The halo is attributed to neutrons occupying the 2p3/2 orbital, thereby vanishin...
