A New Representation of the 3C Model in the Quasi-Sturmian Approach to Ionization of Helium by Proton Impact / S.Zaytsev, Yu.Popov, [a.o.]. – Text : electronic // Physical Sciences Forum. – 2026. – Vol. 13, No. 1. – P. 10. – URL: https://doi.org/10.3390/psf2026013010. – Bibliogr.: 18.

We investigate the 75 keV proton impact ionization of helium. The convoluted quasi-Sturmian approach is extended to treat both the direct ionization and the electron capture to the continuum by proposing an ansatz for the Coulomb three-body Green’s function operator, for the kernel of which the leading asymptotic form contains the wave function of the 3C model. The resulting 3C-like model is tested numerically. Fully differential cross-sections are calculated for different energy-loss regimes and compared with recent experimental data.
