The reaction /sup 10/B(p,..gamma..) /sup 11/C has been investigated in the energy range E/sub p/ = 0.07--2.20 MeV. The broad resonant structure previously observed in the ground state transition near E/sub p/ = 1.2 MeV has been seen also in ..gamma..-ray transitions to excited states. The observed excitation functions as well as the ..gamma..-ray angular distributions can be explained by assuming several broad overlapping resonances. The low-energy data (E/sub p/<0.6 MeV) reveal the existence of two s-wave resonances at E/sub p/ = 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/sub x/ = 8--9 MeV. The energy range investigated corresponds to the temperature range of T = (0.01--5) x 10/sup 9/ K. The thermonuclear reaction rates deduced from the present results are compared with previously reported values.
