Abstract
Helium single ionization by 3.6 MeV/u Ni{sup 24+} impact was explored in a kinematically complete experiment by combining a high-resolution recoil-ion momentum spectrometer with a novel 4{pi} low-energy electron analyzer. More than 90% of the ``soft electrons`` (E{sub e}> or {approx}50 eV) are ejected in the forward direction in agreement with CTMC predictions. The electron longitudinal momentum is not balanced by the longitudinal momentum change of the projectile but mainly by the backwards recoiling He{sup 1+}-ion. Energy losses of the 0.2 GeV projectiles as small as {Delta}E{sub P}/E{sub P}=3.4.10{sup -7} are observable. (orig.)
