The mass spectra of the lowest S, P and D levels of the self-conjugate (Q{bar Q}) and the non-self-conjugate (Q{bar q}) mesons are studied with the three flavour-dependent static quark-antiquark potentials, belong to the class U(r)=a{sub 1}r{sup {gamma}}{minus}a{sub 2}r{sup {minus}{gamma}}+a{sub 3}, for {gamma}=1, 1/2, 3/4 cases. The non-relativistic form of statistical model is used in the calculations. The leptonic decay widths and decay constants of the vector Q{bar Q} and the psuedoscalar Q{bar q} mesons are estimated by considering the improved version of the Van Royen-Weisskopf formula. Moreover, the binding energy, the form factor and the charge radius of the proton have also been calculated. These results are in reasonably good agreement with experimental and theoretical findings. 21 refs., 6 tabs.
