The Mark III accelerator operated with good reliability in spite of increasing frequency of the occurrence of water leaks in the rf loads. The loads are being replaced with a leak proof variety on a schedule which interferes very little with Mark III operation for research. Research with Mark II continued as usual. The Mark III electron scattering program has recently installed auxiliary magnets so that the 72 inch spectrometer can measure electrons scattered at 180 degrees. With this apparatus the elastic scattering from the magnetic octupole moment of Be9 and B11 has been studied as a function of momentum transfer. These experiments give for the first time a method of studying in detail the space distributions of the static magnetic moments of light nuclei. The colliding beams experiment is still experiencing difficulties from beam loss or beam cross section increase caused by beambeam interactions. A visit by two Russian physicists from Novosibirsk revealed that their e- - e- colliding beams experiment is subject to similar difficulties.
