Convergent close-coupling method: a 'complete scattering theory'

摘要

It is demonstrated that a single convergent close-coupling (CCC) calculation of 100 eV electron impact on the ground state of helium is able to provide accurate elastic and inelastic (n (<=) 3 levels) differential cross sections, as well as singly-, doubly-, and triply-, differential ionization cross sections. Hence, it is suggested that the CCC theory deserve the title of a 'complete scattering theory'. 28 refs., 5 figs. (Atomindex citation 27:038954)
