Measurement of the $K_L$ nuclear interaction length in the NaI(Tl) calorimeter

Abstract

In the study of the reaction $e^{+}{e}^{-}\to K_S{K}_L$ at the VEPP-2M $e^{+}{e}^{-}$ collider with the SND detector the nuclear interaction length of $K_L$ meson in NaI(Tl) has been measured. Its value is found to be 30--50 cm in the $K_L$ momentum range 0.11--0.48 GeV/$c$. The results are compared with the values used in the simulation programs GEANT4 and UNIMOD.
