Abstract
The halo structure of is studied using -removal reactions on C and Pb targets at . A combined analysis of the cross sections of these nuclear and Coulomb dominated reactions that feed directly the ground-state reveals to have a small neutron separation energy, , and spin-parity . Consistency of the data with reaction and large-scale shell-model calculations identifies as deformed and having a significant -wave halo component, suggesting that halos are more frequent occurrences at the neutron drip line.
