S>The excitation functions for radiative proton capture reactions leading to the N/sup 13/ ground state (C/sup 12/(p, gamma /sub o/)N/sup 13 /) and to a state at 3.5 Mev in N/sup 13/(C/sup 12/(p, gamma /sub 2/)N/sup 13*/) were measu red with incident proton energies from 10 to 48.5 Mev. The excitation function for the ground state reaction shows strong peaks at excitations in N/sup 13/ of 13, 20, and 32.5 Mev. If these are interpreted as the regions of strong E1 radiative strength the results are in good agreement with the T = 1/2 dipole states predicted in the shell model calculations of Easlea. The excitation function for radiative capture to the excited state has a peak at an excitation of 24.5 Mev in N/sup 13/ and above that energy falls slowly with increasing energy, being still detectable at the maximum proton energy of 48.5 Mev.
