$the various processes are compared with those calcu- lated on the basis of the statistical model from the formula of Lepore and Stuart.5 The experimental value Of 01/0-2, where a-1 and O2 are the cross sections for single and double ir production, respectively, is compared with that predicted by the statistical model and the excited-state model. A similar comparison is made for the experimental value of oi(wr+)/1o-j(7r1); both results are compatible with the two theories. Figures 1 and 2 show the c.m. angular distribution for single r production of ir+ and 7rw mesons with respect to the nucleon of lower energy. The evidence of angular correlation is not reconcilable with the present formu- lation of the statistical theory and suggests a production process characterized by the emission of the ir meson by a single nucleon. In Fig. 3 are plotted the experimental values calcu- lated for the decay of an excited nucleon into a nucleon and a w+. There is some evidence of a peak around 150 Mev as suggested by the Peaslee model. However, this model gives fractional weights of 4 and . for the intermediate compound states (Tz,,T2) = (3/2, - 1/2) Q(Mev) FIG. 3. Q$
