Electron loss to the Continuum in the Projectile ionization for Positronium - Helium atom collision
Susmita Roy, C. Sinha
The dynamics of the electron loss to the continuum (ELC) from the light neutral projectile positronium (Ps) atom in collision with the He atom is studied in the framework of the po…
