Spectra of ..gamma.. rays from radiative capture of neutrons have been measured in weak p-wave resonances at 0.88 eV (/sup 81/Br), 1.33 eV (/sup 117/Sn), and 0.75 eV (/sup 139/La). We have determined the intensities of secondary ..gamma.. transitions, the partial ..gamma.. widths of resonances for emission of hard ..gamma.. rays, and the cross section for radiative capture of thermal neutrons in /sup 117/Sn (sigma/sub ..gamma../ = 1.32 +- 0.18 b). The isotopic assignment of the 0.88-eV p resonance in Br indicated above has been established. The results are discussed in connection with the question of nonconservation of spatial parity in reactions induced by neutrons.
