Resumo

Breakup reactions were used to study the ground-state configuration of the neutron-rich isotope 23O. The 22O fragments produced in one-nucleon removal from 23O at 938 MeV/nucleon in a carbon target were detected in coincidence with deexciting γ rays. The widths of the longitudinal momentum distributions of the 22O fragments and the one-neutron removal cross sections were interpreted in the framework of a simple theoretical model which favors the assignment of Iπ=1/2+ to the 23O ground state.Received 15 December 2003DOI:https://doi.org/10.1103/PhysRevLett.93.062501©2004 American Physical Society
