A calculation is made of the energy levels of the bound states of a strange quark and its antiquark with an interaction which includes an attractive Coulomb potential term, a confining linear potential, and spin-orbit, quadratic-orbit, spin-spin, and quadratic-spin interactions. Good agreement is obtained with observed mesons, and the existence of other mesons is predicted.
