    "abstract": "The attenuation factor F responsible for the decay out of a superdeformed\n(SD) band is calculated with the help of a statistical model. This factor is\ngiven by 1/F = (1 + Gamma(down) / Gamma(S)). Here, Gamma(S) is the width for\nthe collective E2 transition within the superdeformed band, and Gamma(down) is\nthe spreading width which describes the mixing between a state in the SD band\nand the normally deformed (ND) states of equal spin. The attenuation factor F\nis independent of the statistical E1 decay widths Gamma(N) of the ND states\nprovided that the Gamma(N) are much larger than both Gamma(down) and Gamma(S).\nThis condition is generically met. Previously measured values of F are used to\ndetermine Gamma(down).",
