Аннотация:Scattering of protons with transversal polarization $p_y^p$ on deuterons
with tensor polarization $P_{xz}$ provides a null-test signal
for time-reversal (T) invariance violating but parity (P) conserving effects.
We calculate the corresponding null-test observable at beam energies $100$--$1000$ MeV
within the spin-dependent Glauber theory considering T-violating P-conserving nucleon-nucleon interactions.
The $S$-wave component of the deuteron wave function as well as the $D$-wave
are taken into account and the latter is found to play an important role for the
magnitude and the energy dependence of the observable in question.

Specifically, with inclusion of the $D$ wave the maximum of the expected signal is
shifted to higher beam energies, i.e. to $700-800$ MeV.
