The operation of the electron synchrotron is described. The tasks performed by various groups are briefly described. The experiments being carried out with the electron synchrotron are summarized. The differential cross sections of mesons ( pi /sup 0/ photoproduced in H/sub 2/ were measured at 600 to 800 Mev for center-of-mass angles of 57 and 90 deg ; a narrow resonance was detected at approximately 700 Mev. Some preliminary measurements of the Compton effect of protons with a pi /sup 0/ background are reported. Fine structure is found in the intensity of the bremsstrahlung produced by 1000Mev electrons in Si crystals when plotted versus the angles of the electrons and gamma rays with respect to the crystalline axis STA1 1 1!. The angular distribution of the gamma + p - n + pi /sup +/ cross section is given for photon energies between 600 and 700 Mev. Equipment being devised for work on proton polarization and parity conservation in meson ( pi ) photoproduction is described. Messurements on the gamma + p - LAMBDA /sup 0/ + K/sup +/ process at energies of 900 to 1050 Mev are reported. Work performed in various projects on meson ( pi ), ( mu ), and (K) photoproduction in H/sub 2/, D/sub 2/, and other nuclei are summarized. (D.L.C.)
