“…It is important to discern between the acceptance of the experiment given by the bin sizes employed in the analysis of the data (as described above) and the uncertainties in the measurement of the particles' momenta related to the actual experimental conditions. In figure 4, we present the CDW and CTMC results corrected by considering the uncertainties of the measured data (Fischer et al 2003, Moshammer 2003. The one standard deviation experimental uncertainty in the determination of the momentum of the recoil ion is approximately ±0.22 au for the component perpendicular to the incident velocity v and ±0.1 au in the parallel component.…”

Single ionization of helium by impact of 3.6 MeV u −1 Au 53+ ions is investigated by means of quantum-mechanical and classical methods. Calculations of fully differential cross sections are compared with recently published data for ionization of low-energy electrons as a function of the momentum transferred by the projectile to the target system. A description of initial and final states of the He atom in terms of a Hartree-Fock potential provides an improvement over previous hydrogen-like models. The present results show that inclusion of the resolution and uncertainties present in the experiment has a major influence on both the shape and magnitude of the cross sections. The effect of four bodies and electron-electron correlation is also investigated. However, after including the experimental conditions into the calculations, the three-and four-body results present similar behaviour.

Single ionization of helium by impact of 3.6 MeV/u Au 53+ ions is investigated by means of quantum and classical methods. Calculation of fully-differential cross sections are compared to recently published data for ionization of low-energy electrons as a function of the momentum transferred by the projectile to the target system. The results show that inclusion of the resolution and uncertainties present in the experiment has a major influence on both the shape and magnitude of the calculated cross sections. The effect of using a two-electron model for the He target along with including electron-electron correlation are also investigated. However, after incorporating all the experimental conditions within the calculations, the one-and two-electron results present similar behavior.
