César Lattes improved the measurement of particle tracks in nuclear emulsions and helped establish the pion-muon decay sequence. His own recollection describes range–energy calibrations and plates exposed at high altitude. Plates treated with borax preserved substantially more latent events than untreated controls, an unexpected practical advantage. More complete stopping-and-decay tracks then supported a comparison of the parent and daughter masses, showing why detector chemistry and calibration mattered to a particle discovery.[ref]
