Population of Be-13 in a nucleon exchange reaction
The neutron-unbound nucleus Be-13 was populated with a nucleon exchange reaction from a 71 MeV/u secondary B-13 beam. The decay-energy spectrum was reconstructed using invariant mass spectroscopy based on Be-12 fragments in coincidence with neutrons. The data could be described with an s-wave resonance at E-r = 0.73(9) MeV with a width of Gamma(r) = 1.98(34) MeV and a d-wave resonance at E-r = 2.56(13) MeV with a width of Gamma(r) = 2.29(73) MeV. The observed spectral shape is consistent with previous one-proton removal reaction measurements from B-14.
