    "abstract": "The nuclear collective response is investigated in the framework of a doorway\npicture in which the spreading width of the collective motion is described as a\ncoupling to more and more complex configurations. It is shown that this\ncoupling induces fluctuations of the observed strength. In the case of a\nhierarchy of overlapping decay channels, we observe Ericson fluctuations at\ndifferent scales. Methods for extracting these scales and the related lifetimes\nare discussed. Finally, we show that the coupling of different states at one\nlevel of complexity to some common decay channels at the next level, may\nproduce interference-like patterns in the nuclear response. This quantum effect\nleads to a new type of fluctuations with a typical width related to the level\nspacing.",
