Abstract
The aim of the present study was to measure the double differential cr oss section (DDCS) for the electron ejection as a function of electron energy at 0-degree observation angle in H+ --> He collisions. Having in mind that the experimental and theoretical shape parameters of the DDCS known in the literature are rather scattered, we made a systemati c study in the projectile energy range 75-1400 keV. The total electron yield and the shape parameters of the DDCS were determined and compar ed with the corresponding values from 2nd order OBK, CDW and CDW-EIS t heories. A further aim of this work was to check whether the velocity of the projectile and that of the electrons at the maximum of the cusp peak are indeed equal.
