摘要：

The P-odd effect in the radiation cross section of capture of longitudinally polarized neutrons in a sample of natural lead is measured. The experiment was performed at PF1B facility at the Institut Max von Laue-Paul Langevin. The neutron polarization P (n) was 92%, the total flux of polarized neutrons was similar to 3 x 10(10) n/s, and the mean neutron wavelength was lambda = 4.7 . Taking into account "0-test" we estimated the asymmetry: a (gamma)(Pb-nat) = (2.3 +/- 3.5) x 10(-7), i.e., alpha (gamma) a parts per thousand currency sign 8.1 x 10(-7) at 90% confidence level.
