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 J^\ensuremathπ=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 J^\ensuremathπT=3(+)? resonance at 22 MeV is determined to be 3^\ensuremath-0, and the experimental 1^\ensuremath-? (at 19 MeV) and 4^\ensuremath-? resonances are determined to be isospin 0.
