Abstract
A three-vector a pt (σ n [k α × s γ]) correlation of the neutron beam polarization directions σ n , α-particle momentum k α, and γ-quantum circular polarizations s γ in 10B(n, α1γ)7Li reaction (E γ = 478 keV) is proposed as a means of searching for the simultaneous time-reversal invariance and space parity (PT-invariance) violation. An expression for a pt coefficient in the αγ cascade is presented. Masking effects, sensitivity of the proposed experiment, and its realization prospects are discussed.
