Measurement of the KL nuclear interaction length in the NaI(Tl) calorimeter
© 2015 IOP Publishing Ltd and Sissa Medialab srl. 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 KL meson in NaI(Tl) has been measured. Its value is found to be 30-50 cm in the KL momentum range 0.11-0.48 GeV/c. The results are compared with the values used in the simulation programs GEANT4 and UNIMOD.
