Abstract : The spectrum of the upsil on meson system I consists of bound stales of a bottom quark hand ami-bottom quark bcalled bottomonium. Upsilon is a massive meson or about 9.46GcV, It was discovered by resonance peaks produced ut certain energies in experiments involvin g the production of lepton pairs. And the higher energy peaks are the excited ~Iales of I . In this work, we calculate the rna" spectrum ofthix system, by using Dirac cquarion. which is a rcluri visti c equation . and holds for spin 11'2 part Id es. We assume two suit able models of interaction poiemial-, bet ween the consti tueru quarks of )~ sy\lcm The prohlem is solved by using WKB-method. We develop a computer program to obtain the energy eigenvalues I'm differeut values of K quantum number and fur n =O. I. '2 and 3. r:i nally, we compare our results with experimental val uex, to show a good agreement especially fm"'~ =I .
