TL;DR
This study investigates the unbound nucleus 13Be using nucleon-exchange reactions, reconstructing its decay energy spectrum to identify resonances and compare with previous measurements.
Contribution
It reports the first detailed decay energy spectrum of 13Be populated via nucleon exchange, identifying s- and d-wave resonances with specific energies and widths.
Findings
Identification of s-wave resonance at 0.73 MeV
Detection of d-wave resonance at 2.56 MeV
Spectral shape consistent with previous 14B removal data
Abstract
The neutron-unbound nucleus 13Be was populated with a nucleon-exchange reaction from a 71 MeV/u secondary 13B beam. The decay energy spectrum was reconstructed using invariant mass spectroscopy based on 12Be fragments in coincidence with neutrons. The data could be described with an s-wave resonance at E = 0.73(9) MeV with a width of Gamma = 1.98(34) MeV and a d-wave resonance at E = 2.56(13) MeV with a width of Gamma = 2.29(73) MeV. The observed spectral shape is consistent with previous one-proton removal reaction measurements from 14B.
