Close-coupling calculations of elastic and inelastic positron-helium scattering
(Iop Publishing Ltd, 2014)
Positron-helium scattering at medium energies
(Elsevier B.V., 1996-11-15)
We present results for medium-energy elastic, inelastic [transition to He(1s2(1)s), He(1s2(1)p), He(1s3(1)s), and He(1s3(1)p) states], capture [to Ps(1s), Ps(2s), and Ps(2p) states of the positronium (Ps) atom] and total ...
POSITRON-HELIUM SCATTERING IN THE CLOSE-COUPLING APPROACH
(Elsevier B.V., 1995-06-16)
We present results for low-energy elastic S-, P-, and D-wave phase shifts, capture and total cross sections of positron-helium scattering with different basis sets in the close coupling approach using realistic wave functions ...
Close-coupling calculations of positronium formation in positron-helium scattering
(Iop Publishing Ltd, 1998-07-14)
Positronium (Ps) formation in positron-helium scattering has been investigated in different partial waves at medium energies including the Ore gap region using the close-coupling approximation with realistic wavefunctions ...

Double ionization of helium by 2-keV electrons in equal- and unequal-energy configurations
(American Physical Society, 2016-03)
We present theoretical and experimental fully differential cross sections, in coplanar scattering geometry, for the double ionization of helium by electron impacting at 2 keV. The observed structures for both equal and ...
