This group constituted the first meeting in Heidelberg, on Jan. 12, 1977, of the GALLEX solar-neutrino-absorption experiment planning team. From left, Till Kirsten (PI of GALLEX), Donald Clayton (von Humboldt Senior Visiting Scientist for 1977), Raymond Davis Jr. (PI of the Cl neutrino-absorption experiment), Wolfgang Haempel, and Oliver Schaeffer (Brookhaven). The site is Kirsten's office at Max Planck Institut fuer Kernphysik. The wall photograph is of Josef Zaehringer, director of the Institute program in meteoritics and lunar studies until his sudden death in an auto accident. This room was named in his honor. The GALLEX experiment became a success, and heightened the "solar-neutrino problem". Clayton was beginning a period of seven years of sharing of this office at Kirsten's invitation; but he later withdrew from team membership owing to his committments to Compton Gamma Ray Observatory. See the companion photo of Clayton in this same location and date on this site. See other photos of Kirsten and Clayton in the Zaehringer Zimmer in 1981, but within which the wall photograph of Zaehringer has moved from this wall (behind Clayton's desk) to the opposite wall (behind Kirsten's). Oliver Schaeffer's death ended his team work.
