摘要
An adaption of the convergent close-coupling method to calculation of differential ionization cross sections [I. Bray and D.V. Fursa, Phys. Rev. A 54, 2991 (1996)] is analyzed in the context of the Temkin-Poet model. The asymptotic scattering wave functions and the unitarity relation are given for the model. Our analysis is used to reconcile the recent criticism by G. Bencze and C. Chandler [Phys. Rev. A 59, 3129 (1999)] of the formulation of Bray and Fursa. It is concluded that the use of "distinguishable" electrons as proposed by Bray and Fursa is not essential in the close-coupling description of ionization.
