Measurement of the angular dependence of the polarization of the recoil protons from the photoproduction of neutral pions on hydrogen at proton energies between 240 and 420 MeV

Althoff, K.H. ; Finken, D. ; Minatti, N. ; et al.
Phys.Lett.B 26 (1968) 677-678, 1968.
Inspire Record 1392747 DOI 10.17182/hepdata.29304

New measurements of the polarization of the recoil protons from the reaction γ + p → π o + p are reported for the region of the first resonance. These measurements are an extension of earlier experiments, done on the 500 MeV-electron-synchroton. More data have been taken at photon energies of 240, 300, 360 and 420 MeV.

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

Achasov, M.N. ; Beloborodov, K.I. ; Berdyugin, A.V. ; et al.
JINST 10 (2015) P09006, 2015.
Inspire Record 1392011 DOI 10.17182/hepdata.69471

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.
