Emergence of Quantum Vortices in the Ionization of Helium by Proton Impact, and How to Measure Them

Emergence of Quantum Vortices in the Ionization of Helium by Proton Impact, and How to Measure Them

This study investigates how the presence of quantum vortices affects the ionization cross-section of helium atoms by 75 keV proton impact, with special attention to the region near the electron capture to the continuum (ECC) cusp. It has been found that these vortices cause a significant reduction i...
