Emission of low-energy particles from highly excited nuclei
1980
We report an experimental study of the multiplicity of emission and the energy spectrum of evaporative charged particles (mainly protons) in disintegration of the nuclei of nuclear emulsion induced by primary hadrons with energies 67, 200, and 400 GeV. The experiments show that with increase of the excitation energy of the target nucleus the probability of emission of several short-range protons (R< or =100 mm) increases, and the emission of these particles is identically probable for the light and heavy nuclei of the emulsion. With increase of the energy of the incident hadrons, the locations of the maxima of the energy spectra of the evaporation particles (E<26 MeV) shift toward lower energies and consequently the energy distribution of the protons approaches the energy distribution of the neutrons.
