Abstract
By giving the explicit calculations in the first order of the strong coupling we extend this method to higher orders and show that there will always appear new excited mesons at higher order, independent of the approximation used. These states are analogous to be bound states of a confining potential, which has an infinite barrier at radiusr=a.
