“…It follows from [1,13,14] that this new approach fits the experimental data pretty well. In addition, the analysis of integrated cross section in [15,16] using CDSD shows that previous discrepancies can be resolved if capture to the holes of the target nuclei is taken into account.…”

In the original direct-semidirect (DSD) model for the radiative capture of nucleons in the region of the giant dipole resonance, the complex particle-vibration coupling function was introduced phenomenologically and the real and imaginary strengths V 1 and W 1 determined from the comparison of the calculated and rather scarce experimental results. One can, on the other hand, extract an analytical expression for this coupling from the recent formulation of the consistent DSD, in light of which we conclude that the strengths V 1 and W 1 are both spin and mass dependent. Such dependence has not been known before, while the real and the imaginary parts of the coupling function turn out to be indeed of the volume and the surface peaked shapes, respectively, as used in previous versions of the model. The mass dependence deduced is for the capture to the ground states V 1 = 16.8A 1/3 MeV for the real and W 1 = 16.1A 1/3 MeV for the imaginary part.

“…factors were introduced. Subsequently, it was demonstrated that by their usage a consistent description of the available data with DSD theory can be achieved throughout the nuclear chart (see [15] and references therein). We, therefore, included our factors in Eq.…”

High resolution spectra from fast proton radiative capture in 208 Pb are presented for three energies of the incident protons: 14.8, 15.7, and 16.9 MeV. The collected spectra were analyzed with emphasis on the region of capture to unbound states in order to search for possible structure and to study the competition between two basically different phenomena: the statistical process versus the fluctuation effects in radiative capture to unbound final states. In the energy region of incoming protons considered in our experiment, the statistical processes modeled with a Hauser-Feshbach calculation dominate. The spectra of primary γ rays, coincident with the low energy one from the decay of the f 7/2 single-particle state, show a prominent structure which is predominantly of g 9/2 character. The calculations of continuum spectra based on the extended direct-semidirect model and the Hauser-Feshbach statistical approach successfully reproduce the experimental data.
