Photoneutron studies of E1, M1, and E2 excitations in /sup 13/C

; ; ; ;

The angular distribution for the /sup 13/C(..gamma..,n/sub 0/)/sup 12/C reaction was observed in the energy region 6.5 to 9.3 MeV and at angles of 90/sup 0/ and 135/sup 0/. The photoneutron measurements were analyzed in terms of a multilevel R-matrix formalism. The /sup 12/C(n,n)/sup 12/C reaction channel was explicitly included in this analysis. The effects of potential capture were directly observed in the photoneutron spectra. The ground-state radiative widths for resonances in this energy region were deduced from the R-matrix interpretation of the results. The ground-state transition probabilities for E1 excitations at 7.69 and 8.19 MeV were found to be in good agreement with the predictions of the weak-coupling model.
