We calculate the
mass spectrum, the splitting values and some other properties in the
framework of the semirelativistic equation by applying the shifted
large-N expansion technique. We use seven different central potentials
together with an improved QCD-motivated interquark potentials calculated
to two loops in the modified minimal-subtraction scheme. The parameters of these potentials are fitted to generate the semirelativistic bound states of
quarkonium system in close conformity with the experimental and the
present available calculated center-of-gravity (c.o.g.) data.
Calculations of the energy bound states are carried out up to third
order. Our results are in excellent fit with the results of the other
works.
