Abstract

Particle capture calculations to 4He have been performed within the framework of the continuum shell model with full correction for target recoil and with non-central forces. Differential cross section and polarization results are presented for both neutron and proton capture. The calculations include E1, E2 and M2 contributions. The calculated ratio of total cross sections, σ(γ, p)/σ(γ, n) is close to one above Ep = 4 MeV. Possible corrections to this ratio are discussed. The calculated E2 strength is very broad and structureless. The maximum E2 strength is near 63A13 MeV excitation. Of this E2 strength virtually all is 1D2.

      Although the residual interaction is different in the two cases, GOE provides a good approach to the central part of the spectra in both cases. Common in these two cases is, however, the large number of avoided level crossings (see Ref. [43] for a microwave cavity). Thus, the avoided level crossings seem to be more important than the residual interaction for the spectra to show GOE features [53].
