One-neutron knockout of 23O
Artikel i vetenskaplig tidskrift, 2005
Breakup reactions were used to study the ground-state configuration of the neutron-rich isotope23O. The22O fragments produced in one-nucleon removal from23O at 938 MeV/nucleon in a carbon target were detected in coincidence with de-exciting γ rays, allowing to discern between22O ground-state and excited-states contributions. From the comparison of exclusive experimental momentum distributions for the one-neutron removal channel to theoretical momentum distributions calculated in an Eikonal model for the knockout process, and spin and parity assignment of Iπ= 1/2+was deduced for the23O ground state. This result solved the existent experimental discrepancy.
