| الوصف: | We measured the electron capture to the continuum (ECC) peak in the ionization of He atoms by the collision of 50, 100 and 200 keV H+ and 100 keV amu-1 He2+. We exhaustively scanned the double differential cross section between the angles -1.5 degrees to 10 degrees and within the velocities (1+or-0.15) upsilon i where upsilon i is the impact velocity. We propose a new method for analysing the ECC structure which is independent of the spectrometer transmission function modellization and enables a direct comparison with the available theories. Furthermore, we distinguish two regimes for the ionization process, depending on whether the electron velocity is larger or smaller than the projectile velocity. |
