Final State Interactions in Weak Three-Body Decays Calculated in the Impulse Approximation

Abstract

1123An exactly soluble model of the weak three-body decay of a Q+ particle to three daughter O+ particles which interact strongly has been studied by Amado and Noble. The same problem with identical input data is studied in the impulse approximation. The two sets of results are compared to examine the accuracy of the impulse model. The question is studied of how accurately the two-body parameters can be extracted from the weak-decay data using the impulse approximation. § 2. TheoryThe weak-decay amplitude for the G decay IS(1)
