    "abstract": "We discuss the origin of the difference between the harmonic value of the\nwidth of the multiphonon giant resonances and the smaller observed value.\nAnalytical expressions are derived for both the effective width and the average\ncross-section. The contribution of the Brink-Axel mechanism in resolving the\ndiscrepancy is pointed out.",
