The observation of a peak structure in the electron spectra resulting from e++Th,U collisions with a measured FWHM of (3.7 0.5) keV cannot be attributed to a new phenomenon, i.e., the e+e- decay of a neutral particle as recently claimed, because in this case the expected resonance width is broadened to at least 60 keV (FWHM) in the laboratory frame because of the motion of the bound electrons. © 1989 The American Physical Society.
