Abstract

The negative muonium ion, Mu-e-e-, has been produced by double electron pickup as a beam of positive muons passes through thin foils of various materials. The Mu- ions were detected by electrostatically accelerating and analyzing the ions in a magnetic time-of-flight spectrometer. Yields of Mu-, Mu and + as well are reported when + with kinetic energies from 380 to 800 keV impinge on thin Be, Al, and Au foils. A Monte Carlo simulation provides good agreement with the experimental results.
