N2 - Abstract: We present the preliminary measurement of the two-photon η-meson production cross section:. The measurements were carried out by the SND detector at the VEPP-2000 collider in the energy range from 1 to 2 GeV, the integral luminosity of the order of 0.5 fb–1 was used. The η-meson was detected at the six-photon final state, without scattered electrons registration. From the cross section of this process, we extract the two-photon η-meson width. The experimental results obtained can be used to calculate the hadronic contribution to the light by light scattering and to interpret the results of the muon anomalous magnetic moment measurement’s and to calculate the electromagnetic interaction constant at Z boson mass scale.
