Ground- and excited-state scattering potentials for the stopping of protons in an electron gas
(2019) [Artigo de periódico]The self-consistent electron–ion potential V(r) is calculated for H+ ions in an electron gas system as a function of the projectile energy to model the electronic stopping power for conduction-band electrons. The results ... -
Nonlinear stopping effects of slow ions in a no-free-electron system : titanium nitride
(2019) [Artigo de periódico]A recent experimental study of the energy losses of various ions in titanium nitride, in the low-energy range [M.A.Sortica et al. , Sci. Rep. 9 , 176 ( 2019 )], showed a striking departure of the measured values from those ... -
Stopping power of cluster ions in a free-electron gas from partial-wave analysis
(2018) [Artigo de periódico]A nonlinear model for the stopping power of cluster ions based on partial-wave analysis is developed through the generalization of the induced density approach (IDA) model for the interaction of homo-and heteronuclear ... -
Vicinage effect in the energy loss of H2 dimers : experiment and calculations based on time-dependent density-functional theory
(2017) [Artigo de periódico]We present a combined theoretical and experimental study of the energy loss of H2 + molecular ions interacting with thin oxide and carbon films.As a result of quantum mechanical interference of the target electrons, the ...
