Abstract
We present the 1/M relativistic B-S expansion formalism for heavy meso ns, explain its relation to HQET and give further simplified formulas. The numerical results for the decay rates of 1(-) and 0(+) heavy meso ns including the effects of the order 1/M are obtained with a model wh ich has been used successfully to the spectra of heavy mesons.
