摘要：

The Particle Listings 2000 edition gave the recommended value of antiproton mass, for the first time, to be within 5 x 10(-7) in the relative deviation from the proton mass; this can be a test of the CPT invariance. The value was derived by our precision 3-body calculation, using the Gaussian Expansion Method, to analyze the laser spectroscopy data of metastable states in antiprotonic helium atoms taken at CERN. The 2002 edition and the 2003 updated version reported an one-order smaller value, 6 x 10(-8), based on further development of both the experiment and our calculation.
