Effective widths and effective number of phonons of multiphonon giant resonances

We discuss the origin of the difference between the harmonic value of the width of the multiphonon giant resonances and the smaller observed value. Analytical expressions are derived for both the effective width and the average cross section. The contribution of the Brink-Axel mechanism in resolving the discrepancy is pointed out.
