Frederick Reines, now dean of the School of Physical Sciences at the Irvine campus, University of California, has moved his neutrino‐detection equipment to a deeper part of a South African salt mine. Three times as sensitive as it was before, it has moved down 47 meters to a depth of 3300 meters. Reines is running experiments at three different installations: the one in South Africa, another in a salt mine near Cleveland and a third near an AEC reactor in South Carolina. The effort is a collaboration among Irvine, Case Western Reserve (with M.F. Crouch and Robert Woods Jr) and the University of the Witwatersrand (with J.P.F. Sellschop).
