Charged Particles of Energy in Excess of Evaporation Energy from K--Meson Absorption by Nuclei

摘要

It is shown that, upon the stopping of a negatively charged kaon and its absorption by a nucleus, there arise particles whose appearance does not comply with thermodynamic evaporation theory. An identification of these particles by various methods makes it possible to evaluate the nearly identical yields of H-3 and He-3 nuclei. This result may serve as an indication that direct reactions induced by interaction with He-4 are observed in K--meson absorption in nuclei.
