Abstract
Measurements of angular distributions of secondary particles in interactions of high energy primaries of cosmic radiation with the nuclei of photographic emulsion have been performed. A systematic increase in anisotropy of angular distribution in C.M. with increasing primary energy has been stated. It was found that in many high energy jets the number of secondaries in the vicinity ofπ/2 C.M. angle in smaller than that predicted by the theories of Heisenberg or Landau. For explaining these experimental results a model has been introduced in which the secondaries are emitted isotropically from two centres moving in opposite direction in the C.M. system. Some experimental arguments have been given for this isotropy. The relation between the velocity of two centres, the inelasticity coefficient, multiplicity and transversal momenta of secondaries has been discussed.
