The recent discovery of Ds states suggests the existence of radial excitations. Our semirelativistic quark potential model succeeds in reproducing these states within one to two percent of accuracy compared with the experiments, D s0(2860) and D s *(2715), which are identified as 0+ and 1- radial excitations (n = 2). We also present calculations of radial excitations for B/B s heavy mesons. The relation between our formulation and the modified Goldberger-Treiman relation is also described.
