Nuclear structure studies with electrons have entered a new phase of development. In addition to an ongoing program of selected experiments at very high energy at the Standard Linear Accelerator Center (SLAC), an 800-MeV continuous-beam microtron is in operation at Mainz, Germany, with a complement of spectrometers for detecting the scattered electrons and a tagged-photon facility. The Bates Laboratory at the Massachusetts Institute of Technology in Cambridge, where pioneering studies in this field have been carried out since the early 1970s, now has a storage ring where large circulating currents can be directed on a variety of thin gas targets. This configuration has led to an entirely new class of experiments, as first demonstrated in Novosibirsk, Russia, and at the NIKHEF Laboratory in Amsterdam.
