[en] The major 1989 efforts have been mainly on two experiments at TRIUMF. One was a search for events where the leptonic flavor number conservation law would be violated. The second was an attempt to produce muonic hydrogen and muonic deuterium into a vacuum, and if there are found a adequate number of muons in the 2s state to measure precision energies. The minor efforts have been on the LAMPF experiment on lepton conservations which has consumed effort only in fabricating equipment, and on the completion of analyses from the experiments with hadronic atoms at LAMPF (pionic atoms) and BNL (kaonic and sigmonic atoms)
