Parity violation in p-wave neutron resonances of 121Sb, 123Sb, and 127I has been measured by transmission of a longitudinally polarized neutron beam through natural antimony and iodine targets. The measurements were performed at the pulsed spallation neutron source of the Los Alamos Neutron Science Center. Five statistically significant parity violation effects were observed in 121Sb, one effect in 123Sb, and seven effects in 127I. The weak interaction rms matrix elements and the corresponding spreading widths were determined.
