Structure of ¹³Be studied in proton knockout from ¹⁴B

NUCLEAR REACTIONS ¹H(¹⁴B, ¹³Be), E=400 MeV/nucleon, [¹⁴B secondary beam produced in ⁹Be(⁴⁰Ar, X), E=490 MeV/nucleon using the GSI-FRS facility]; measured reaction products, Eγ, Iγ, (¹²B)γn-coin, relative-energy spectra of ¹²Be+n by momentum analysis of ¹²Be core ejecta using the ALADIN dipole magnet, a double sided silicon-strip detector and the time-of-flight wall, decay neutrons using Large Area Neutron Detector (LAND), and γ rays by the 4π Crystal Ball scintillation detector. ¹³Be; deduced levels, resonances, J, π, widths by missing-mass and invariant-mass methods. Comparison with previous experimental values.
