Abstract

The attenuation factor F responsible for the decay out of a superdeformed (SD) band is calculated with the help of a statistical model. This factor is given by F = (1 + Γ/ΓS)−1. Here, ΓS is the width for the collective E2 transition within the superdeformed band, and Γ is the spreading width which describes the mixing between a state in the SD band and the normally deformed (ND) states of equal spin. The attenuation factor F is independent of the statistical E1 decay widths ΓN of the ND states provided that ΓN ≫Γ, ΓS. This condition is generically met. Previously measured values of F are used to determine Γ.
