Parity violation in neutron scattering on lead isotopes

On the basis of an analysis of experimental data, it is shown that a subthreshold (negative) p-wave resonance can exist in the ²⁰⁴Pb isotope at E _p =?16 eV. The presence of this resonance may explain unexpectedly large values observed experimentally for the P-odd angle of the rotation of the spin of transversely polarized neutrons about their momentum that are scattered on a natural mixture of lead isotopes. No available data are at odds with the existence of the E _p =?16 eV subthreshold resonance in ²⁰⁴Pb.
