Sharp fluctuations in the coefficents describing the angular distribution and analyzing power in the reaction /sup 15/N(p/sub pol/,..gamma../sub 0/)/sup 16/O are observed near E/sub ..gamma../MeV. These correspond to structure in the total cross section. All these structures can be fitted by introducing a narrow secondary doorway state interfering with the primary giant dipole resonance of /sup 16/O.
