Reduced widths for nucleon and deuteron emission from the positive parity (T = 1/2) states in the region of 16 to 20 MeV excitation in the mass-5 system have been calculated using the R-matrix theory. Shell model wave functions were employed to describe the relevant states. Excellent agreement is obtained with various aspects of the experimental results on the well-established 3/2+ resonance at 16.6 MeV. Values for the proton and deuteron partial widths and the γd2/γp2 ratio for the 1/2+ resonance at 18 MeV and 5/2+ resonance at 20 MeV are presented. The calculated proton partial width for the 5/2+ resonance is in the range of values estimated from recent analysis of the p–4He phase-shift data.

Analysis by many-level R-matrix theory of the d-wave "'-'" scattering phase shift suggests the existence of broad 2+ excited states of 8Be, but their properties depend sensitively on the assumed channel radius a2. A simultaneous fit to the 9Be(p, d)8Be deuteron spectrum near the 2, 9 MeV peak requires a2 "'" 7�1 fm, while a simultaneous fit to the ",-particle spectra following 8Li and 8B p-decays requires a2 "'" 6� 7 fm. For the best overall fit with a2 = 6�75 fm, the first 2+ excited state is at 2� 84 MeV excitation energy with a width at half maximum of 1�30 MeV. It is shown that data from other reactions which appeared to give much larger widths for this level can be fitted using the same R-matrix parameters. A second 2+ excited state is obtained at about 9 MeV with a width of about 10 MeV. Properties of the narrow 2+ states at 16�6 and 16�9 MeV are also discussed.
