Description
Total and single differential cross sections for electron impact ionization of helium are calculated within the R-matrix method. In addition to ionization of ground state atoms He (1s2) 1S, we consider the initial metastable states He (1s2s) 1S and He (1s2s) 3S for incident projectile energies ranging from threshold to 350 eV. Our calculations include the processes which leave the residual ion in an excited state He+ (nl) up to n = 3. The results are compared with experiments and other theoretical data. (Author)
