Asymmetry ratios in the photoproduction of π + by linearly polarized γ-rays in the energy range 200–400 MeV

Gorenstein, P. ; Grilli, M. ; Soso, F. ; et al.
Phys.Lett. 23 (1966) 394-396, 1966.
Inspire Record 1392866 DOI 10.17182/hepdata.30179

The asymmetry ratio for the process γ + p → n + π + by linearly polarized γ rays are reported for E γ = 200 − 400 MeV and for θ (production angle of π in the c.m. system) = 90°. The experimental results are compared with some recent theoretical predictions.

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.

Measurement of the polarization of the recoil proton from the photoproduction of neutral pions on hydrogen in the region of the first resonance. I

Althoff, K.H. ; Kramp, K. ; Matthay, H. ; et al.
Z.Phys. 194 (1966) 135-143, 1966.
Inspire Record 1385256 DOI 10.17182/hepdata.16667

The polarization of the recoil proton from the reaction 7+p--->~pi0+p has been measured using liquid helium as polarization analyser. The photon energy has been varied between 250 and 360 MeV, the pion angle (CM) between 58 and 100.
