Neutron transmission tests of time reversal invariance on resonance have attracted considerable attention because of the large enhancement of symmetry violating observables. The P-even T-odd five fold correlation (FC) term s {center_dot} (I x k)I {center_dot} k is measured with an aligned target. We discuss how to identify suitable resonances in an aligned target by means of the deformation effect. We focus on neutron transmission through aligned {sup 165}Ho, and consider the possibility of locating small d-wave admixtures in weak, predominantly s-wave resonances. We estimate the sensitivity of the FC test to {alpha}{sub T}, the ratio of the T-odd to T-even parts of the effective nucleon-nucleon interaction.
