The reaction ' B(p, y}"C has been investigated in the energy range E~=0.07 -2.20 MeV. The broad resonant structure previously observed in the ground state transition near E"=1. 2 MeV has been seen also in y-ray transitions to excited states. The observed excitation functions as well as the y-ray angular distributions can be explained by assuming several broad overlapping resonances.The low-energy data (Ep & 0.6 MeV) reveal the existence of two s-wave resonances at Ep =0.010 and 0.56 MeV. Spectroscopic factors for several final states have been obtained from observation of direct capture processes to them; they are in fair agreement with results from stripping reaction studies. The present data also provide information on partial and total widths of the states at E"=8 -9 MeV. The energy range investigated corresponds to the temperature range of T=(0.01 -5) &&10 K. The thermonuclear reaction rates deduced from the present results are compared with previously reported values.' NUCLEAR REACTIONS ' B(p,y), Ep =0.07 -2.20 MeV; measured y yield for ' "C states up to E"=10. 7 MeV. Deduced resonance parameters, branching ratios, and direct capture contributions for proton-unbound states; deduced spectroscopic factors, I y/I t t and I ", for several a-unbound states. Calculated thermonuclear reaction rate for T=(0.01 -5) & 10 K.
