Atomic Beams lab. The lab was under the nominal direction of J.R. Zacharias who had been, with Norman Ramsey, a student of I.I. Rabi (Nobel Prize in Physics winner in 1944) who pioneered atomic beam work ... the other hand was very personable. I learned the field from Ramsey’s encylopedic book: ” Molecular Beams ” [2] so I had great respect for him ...
