One- and two-neutron removal cross sections of ²⁴O

NUCLEAR REACTIONS ⁹Be(²⁴O, ²³O), (²⁴O, ²²O), E=92.3 MeV/nucleon, [secondary ²⁴O beam from ⁹Be(⁴⁸Ca, X), E=140 MeV/nucleon primary reaction, and using A1900 fragment separator at NSCL-MSU]; measured reaction products using S800 magnetic spectrograph, time of flight, parallel momentum distributions, and inclusive σ for one- and two-neutron removals. ^22,23O; deduced levels, J, π, spectroscopic factors. ²⁴O; deduced spherical, doubly-magic structure. Comparison with eikonal reaction model plus shell model calculations using USD-B interaction and the sd model space.
