On test of T invariance in the interaction of slow neutrons with aligned nuclei

Study of five-fold (P even, T odd) correlation in the interaction of slow polarized neutrons with aligned nuclei is a perspective way to test time reversal invariance due to expected enhancement of T violating effects in compound resonances. Possible nuclear targets are discussed which can be aligned both dynamically as well as by 'brute force' method at low temperature. Statistical estimation is performed of five-fold correlation for low lying p wave compound resonances of the 121Sb, 123Sb and 127I nuclei. It is shown that significant improvement can be achieved for bound on intensity of fundamental parity conserving time violating (PCTV) interaction
