摘要
An interesting type of 2-step reaction is that illustrated by A(d, n)B*, B* → C + c, i.e., a direct reaction to a resonant final state B*, which subsequently decays. We are especially interested in the situation in which the resonances B* are sufficiently dense in energy that they overlap, Γ > D, and we present a formalism for calculating the energy-averaged fluctuation cross section to any of the final channels (c + C). In particular, its application to the case in which the states B* are modulated by a doorway, (e.g., an isobaric analog state with fine structure) is worked out in some detail. © 1979.
