Abstract : Energy distribution measurements on 20 keV beams of 12C -, 32S-, 127I-, H- and 160-have shown no obvious differences between H- and 16O- on the one hand, which are believed to be produced in an adsorbed layer on the target, and 12C -, 32S- and 127I- on the other which are part of the target material. All spectra have a single peak and a FWHM of the order of 10-12 eV. The significance of the energy distribution in the calculation of beam brightness is also discussed.
