An interaction of nucleons at an energy between 10¹⁴ and 10¹⁵ eV/nucleon

Abstract

A jet (0+14)α with primary energy {3.3 ^{+ 5.3}_{− 2.2} }. 10¹⁴ eV/nucl. was observed in the “I”-stack. An interaction with very small multiplicity (n _s =3or 4)found in the axis of the jet is probably caused by another nucleon from the α-primary. 10 particles of the narrow cone have opening angles of some 10⁻⁴ radians, 4 particles in the diffuse cone are emitted at angles of a few 10⁻² radians. A pronounced anisotropy exists in the C. M. system. The coefficient of inelasticity ≈ 0.1was calculated directly extrapolating the measured energies of secondaries. The interpretation of the whole event is in good agreement with Heisenberg's theory of multiple production of particles.
