Description
Energies, total and partial widths, and reduced width amplitudes of 8Be resonances up to an excitation energy of 26 MeV are extracted from a coupled-channel analysis of experimental data. The presence of an extremely broad Jπ=2+ 'intruder' resonance is confirmed, and new 1+ and very broad 4+ resonances are discovered. A previously known 22-MeV 2+ resonance is likely resolved into two resonances. The experimental JπT=3(+)? resonance at 22 MeV is determined to be 3-0, and the experimental 1-? (at 19 MeV) and 4-? resonances are determined to be isospin 0
