The process γγ→π+π- was measured using the detector MD-1 at VEPP-4. The two-photon reactions e+e-, μ+ μ- and π+ π- pair production were separated using scintillation counters, Cherenkov counters and shower-range chambers. A radiation width G{cyrillic}γγ(f2(1270))=3.1±0.35±0.35 keV was obtained. © 1992 Springer-Verlag.
