Kinematical calculation of Λ-nucleon stimulation reaction for hyperfragments of mass A=50

Abstract

Energy spectra of fast protons (E≥30 MeV) have been calculated for hyperfragments of mass A=50, from Λ-proton and Λ-neutron stimulation processes respectively. It has been concluded by comparing with experimental energy spectrum, that Λn/Λp stimulation ratio is ~5. It has been estimated, from this ratio, that the emission frequencies of two fast protons, from Λ-single nucleon stimulation, both with E≥20 MeV and with E≥30 MeV, are ≈3·3% and ≈1.7% respectively.
