General formulas for decay widths of heavy mesons with arbitrary spin and parity to the heavy meson ground state plus a {pi} or {ital K} are derived in the leading order of the 1/{ital M} expansion in the relativistic BS equation. Numerical results for various partial decay widths of 1{sup +}, 2{sup +} doublets in the {ital D}, {ital D}{sub {ital s}}, {ital B}, and {ital B}{sub {ital s}} series are obtained with a kernel used previously to obtain the spectra of low-lying states in these series, in good agreement with experiments. The results are in satisfactory agreement with the experimental data when they are available.
