    "abstract": "We describe the decay out of a superdeformed band using the methods of\nreaction theory. Assuming that decay-out occurs due to equal coupling (on\naverage) to a sea of equivalent chaotic normally deformed (ND) states, we\ncalculate the average intraband decay intensity and show that it can be written\nas an ``optical\u0027\u0027 background term plus a fluctuation term, in total analogy\nwith average nuclear cross sections. We also calculate the variance in closed\nform. We investigate how these objects are modified when the decay to the ND\nstates occurs via an ND doorway and the ND states\u0027 statistical properties are\nchanged from chaotic to regular. We show that the average decay intensity\ndepends on two dimensionless variables in the first case while in the second\ncase, four variables enter the picture.",
