  • Abstract The (e,2e) triple differential cross-sections for ionization of helium leading to the ground ( n =1) and first excited ( n =2) states of the ion are measured under high energy asymmetric Bethe-ridge kinematics, at scattered and ejected electron energies of 5500 and 75 eV respectively. With respect to older experiments, the present data are free from electron distortion effects. Hence, when compared with calculations using different correlated wavefunctions, it is found that the best… CONTINUE READING
