FIG. 5.

(a) Kinetic-energy distribution used to fit channels (5a) and (5b)+(6b); (b) used to fit channel (6a); and (c) used to fit channels (5b) and (6b). Boundaries of the shaded area indicate limits of the distributions which still give acceptable fits to the experimental data. An isotropic angular distribution was used to fit channels (5a) and (6a).
