We investigate a random matrix model [Phys. Rev. C {\bf 65} 024302 (2002] forthe decay-out of a superdeformed band as a function of the parameters:$\Gamma^\downarrow/\Gamma_S$, $\Gamma_N/D$, $\Gamma_S/D$ and $\Delta/D$. Here$\Gamma^\downarrow$ is the spreading width for the mixing of an SD state $|0>$with a normally deformed (ND) doorway state $|d>$, $\Gamma_S$ and $\Gamma_N$are the electromagnetic widths of the the SD and ND states respectively, $D$ isthe mean level spacing of the compound ND states and $\Delta$ is the energydifference between $|0>$ and $|d>$. The maximum possible effect of anorder-chaos transition is inferred from analytical and numerical calculationsof the decay intensity in the limiting cases for which the ND states obeyPoisson and GOE statistics. Our results show that the sharp attenuation of thedecay intensity cannot be explained solely by an order-chaos transition.Comment: 4 pages, 4 figures, submitted to Physical Review

Addendum: Attenuation of the intensity within a superdeformed band
