Particle spectrum of Poincare gauge theory is investigated in detail, in particular paticle' s mass and energy. Besides usual graviton, the torsion field gives rise to massive 2+, 2-, 1 +, 1-, o+ and oparticles, each of which obeys the Klein-Gordon equation. We find that there are at most three normal particles, defined by having positive mass and positive energy: namely, only nine possible triplets, (2+, 1+, o-), (2+, 1-, o-), (2+, o+, o-) and their parity conjugate, and (1 +, o+, o-) and its
