113 introduction Chiral symmetry and its breaking play a central role in understanding low energy hadron dynamios. The iso-singlet scalar a-particle appears as a chiral partner of Goldstone T-boson in the linear representation of chiral SU(2)L × SU(2)R group. Its existence has been suggested from va rious points of view[3], however, not approved [1] for long years since of the negative results of the analyses of rT-scattering phase shift [2]. We heve reanalyzed the S-wave rT , phase shift by a
