Аннотация:A component of the total cross section of the deuteron-deuteron interaction connected with the vector polarized (P_y) one initial deuteron and tensor polarized (P_xz) another one constitutes a null-test signal of the T-invariance violation but P-parity conservation. The energy dependence of this signal is calculated here at beam kinetic energies per nucleon of 0.1–1 GeV within the Glauber spin-dependent theory of multiple scattering in the S-wave approximation for the deuteron wave function.
