Search for excited states in ²⁵O

NUCLEAR REACTIONS ²H(²⁴O, ²⁵O), E=83.4 MeV/nucleon, [secondary ²⁴O beam from ⁹Be(⁴⁸Ca, X) primary reaction using A1900 fragment separator at NSCL-MSU facility]; measured ²⁴O particles by a position and energy sensitive charged particle detector and separated based on energy loss and time-of-flight, and neutrons from ²⁵O decay by the MoNA-LISA detector array. ²⁵O; deduced two-body (²⁴O+n) decay energy spectrum by invariant-mass spectroscopy technique, neutron-unbound ground state, L-transfer, asymptotic normalization coefficients, cross section and width of a possible 1/2+ resonance above the ground state. Comparisons with previous experimental results, and with theoretical calculations using complex-energy Gamow Shell Model (GSM) and Density Matrix Renormalization Group (DMRG) method with a finite-range two-body interaction.
