Popis: International audience; We present measurements of P-odd asymmetry of emission of α -particles in the B10(n,α)Li7 nuclear reaction, which are carried out using beams of polarized cold neutrons at Petersburg Nuclear Physics Institute (PNPI, Gatchina, Russia) and Institut Max von Laue – Paul Langevin (ILL, Grenoble, France) nuclear reactors. The α -particle detector is an ionization chamber with insensitive gaseous layer.We measured the P-odd asymmetry coefficient to be equal to αP-oddB10,α=−(11.2±3.4)⋅10−8 .
