Implication

Theoretical modeling study demonstrates convergent cross sections and spin asymmetries in electron-hydrogen collisions, indicating an approximation-free solution for atomic scattering.

Key Points

Investigate the convergence of the close-coupling formalism in electron-hydrogen scattering by systematically expanding target states within an orthogonal Laguerre basis without relying on physical approximations.
Expanded target states into an orthogonal L^2 Laguerre basis, establishing numerical convergence solely by increasing basis size.
Calculated elastic, 2s, and 2p scattering parameters across incident electron energies of 35, 54.4, and 100 eV.
Evaluated integrated cross sections, total cross sections, and T-matrix elements for the first five partial waves.
Achieved convergent elastic, 2s, and 2p differential cross sections without introducing theoretical approximations.
Quantified spin asymmetries and angular-correlation parameters for 2p excitation across all evaluated energy levels.
Derived converged integrated and total cross sections alongside partial wave T-matrix elements through the fifth wave.
