We discuss a model for heavy mesons where the light quark (u or d) moves in the colour-electric field from a heavy quark (c or b) placed in the center of a bag. We calculate energy spectra for pionic and photonic transitions from excited states. The transition amplitudes and the branching ratios between electromagnetic and pionic transitions compare favorably with the limited amount of known experimental data.
