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

详细

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 ³H and ³He nuclei. This result may serve as an indication that direct reactions induced by interaction with ⁴He are observed in K⁻-meson absorption in nuclei.
