Interactions of relativistic clothed heavy ions with solid targets of
various thickness have been studied through measurements of energy spectra
of the convoy electrons at 0°.The peak widths of the convoy electrons in
the laboratory frame have been found to decrease as the target thickness
increases from 25 to 〜500 μg/cm2 and, then, at further thicker targets
get broader due to multiple scattering.
