Abstract：
In the present paper a picture of the baryon-antibaryon system is proposed. If proton, neutron and A hyperon with spin 1/2 form the SU(6) basic particles, then the baryon-antibaryon system must be classified by the SU(6) group (It can be classified into pseudoscalar B Bsystem and vector B Bsystem). The spectrum of the B Bsystem has two characteristics: The "Unitary energy band" and the "strangeness analogy state". In this paper the experimental spectrum of the P psystemwith spin 1/2 and the calculation show that there exist the SU(6) "Unitary energy band" in the P psystem and exist the "strangeness analogy state" between the P psystem and other B Bsystems such as n psystem or BB systems which have strangeness S=±1.
