| Research Abstract |
This project aims to perform the world highest precision test of time reversal symmetry by searching a triple vector correlation in polarized nuclear beta decay, at TRIUMF in Canada. We have developed an electron transverse polarimeter using a drift chamber. Transverse polarization of electrons emitted from beta decay of the polarized 8Li nuclei, produced at TRIUMF-ISAC, is measured by measuring Mott scattering tracks. We have performed the physics data taking in FY2010, obtaining the highest statistical precision. In addition, we have also succeeded to develop the next generation experimental setup which can suppress the systematic errors.
