The single and double ionization of He induced by the collision of high incident energy electrons still remains a challenging problem for theoreticians. Several ab initio calculations (see [1]) of excitation-ionization disagree which each other and with the experimental data [2]. A similar situation is found for the double ionization of He [3]. In this talk, we will provide cross sections for both processes calculated by using the Generalized Sturmian Functions method [4,5]. Comparisons with experimental data [6] and with other calculations will be presented.
