Abstract

Abstract A new semiclassical method, complementary to the WKB one, used to derive quarkonia Regge trajectories within the Schrödinger equation is proposed. Based upon the ħ-expansion, simple recursion formulas are presented. The results computed for some confinement potentials illustrate the speed and accuracy of the technique.
