The processγγπ+π− has been measured with complete particle identification. Cross-sections are presented from near threshold up to the region of thef(1270). In the mass range 0.5–0.7 GeV, crosssections are lower than the Born term predictions and show no evidence for an ε(600). The two-photon width of thef(1270) is found to be in agreement with previous results.

Measurement of the Magnetic Structure Function of the Deuteron at q**2 = 1.0-(GeV/c)**2

At a square of the momentum transfer of 1.0 (GeV/c)2 the elastic scattering of electrons on deuterons has been measured at electron scattering angles of 8°, 60°, and 82°. From these data we have extracted a value of B(q2)=(0.59±1.20)×10−5 for the deuteron. This measurements extends the range in momentum transfer by almost a factor of 2 over the previous measurements.
