RADIATIVE DECAYS OF HEAVY MESONS WITH HEAVY-QUARK SYMMETRY

The radiative decays of heavy mesons are considered in heavy quark sym metry formalism. Introducing the interpolating fields for the heavy me sons we obtain the transition matrix element and the corresponding dec ay widths in the heavy quark symmetry limits. The Isgur-Wise function present in the expression is determined by ISGW quark model. The resul ts obtained agree reasonably well with other estimations.
