摘要

In the study of the reaction e(+)e(-) -> KSKL 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.
