The S-wave model of electron-hydrogen scattering is evaluated using the convergent close-coupling method with an emphasis on scattering from excited states including an initial state from the target continuum. Convergence is found for discrete excitations and the elastic free-free transition. The latter is particularly interesting given that the corresponding potential matrix elements are divergent.

TLDR
This work presents convergent elastic, 2s, and 2p differential cross sections, spin asymmetries, and angular-correlation parameters for the 2p excitation at 35, 54.4, and 100 eV.

Explicit demonstration of the convergence of the close-coupling method for a Coulomb three-body problem.

TLDR
Convergence as a function of the number of states is studied and demonstrated for the Poet-Temkin model of electron-hydrogen scattering and shows that the often-encountered pseudoresonance features in the cross sections are simply an indication of an inadequate target state representation.

USE OF TWO-BODY CLOSE-COUPLING FORMALISMS TO CALCULATE THREE-BODY BREAKUP CROSS SECTIONS

We analyze the consequences of discretizing one of the two continua in three-body breakup to reduce it to a two-body close-coupling problem. We identify the origin of oscillations in the singly

Reply to “Possibility of distinguishing between identical particles in quantum collision processes”

Bencze and Chandler, in the preceding paper, are highly critical of the convergent close-coupling method as applied to the calculation of differential ionization processes. We argue that the
