Abstract

Abstract In a study of 70000 K L o decays a sample of 29000 K L o → π + π − π o decay has been isolated. In the parametrisation of the π o spectrum | M( T o | 2 α | + ( c Q / M k) (3 T o − Q)/ Q (where Q= Q value of the decay and T o = C.M. kinetic energy) c is found to be −5.14 ± 0.09. A linear form for the dependence of M on T o does not fit the data. It was found that the dependence of | M | 2 on X = √3 ( T +− T −)/ Q was weak, where T ± = π +- c.m. kinetic energy.
