文摘

The Dalgarno’s method of perturbation is used to solve the Schrodinger’s equation with the Cornell potential \(V(r)=-\frac{4\alpha _s}{3r}+br+c\). The short range and long range effect of the potential is incorporated in the same wave function by using two scales \(r^{S}\) and \(r^{L}\) as an integration limit. The results for bounds on r.m.s. radii of various heavy flavored mesons are reported.We have also showed the relation between r.m.s. and charge radius of mesons.
