  The Mott polarimetry for T -Violation (MTV) experiment tests time-reversal
symmetry in polarized nuclear beta decay by measuring an electron's transverse
polarization as a form of angular asymmetry in Mott scattering using a thin
metal foil. A Mott scattering analyzer system developed using a tracking
detector to measure scattering angles offers better event selectivity than
conventional counter experiments. In this paper, we describe a pilot experiment
conducted at KEK-TRIAC using a prototype system with a polarized 8Li beam. The
experiment confirmed the sound performance of our Mott analyzer system to
measure T-violating triple correlation (R correlation), and therefore
recommends its use in higher-precision experiments at the TRIUMF-ISAC.
