Role of projectile charge state in convoy electron emission by fast protons colliding with LiF(0 0 1)

Target ionization and projectile ionization differential cross sections are used to calculate the electron emission spectra by fast proton impact on ionic crystal surfaces under grazing incidence conditions. Both bare protons and neutral hydrogen species are considered. We use a planar potential app...
