Angular dependence of energy loss in proton-helium collisions
(1994) [Artículo de periódico]The energy loss of 50 to 250 keV protons scattered under single-collision conditions from He atoms is investigated in terms of its dependence on the angle of scattering. At the higher projectile energies we observe an ... -
Dominant two-center electron-electron interactions in collisions of 120-mev ne(sup 6+) ions with gas targets
(1995) [Artículo de periódico]The target gases H2, He, CH4, N2, Ne, andAr were bombarded by 120-MeV Ne6+ ions to study the 2s-nl excitation from the metastable state 1s 22s2p 3P0 of the Ne6+ projectile. The Coster-Kronig electrons from the transition ... -
Energy loss of proton, [alpha] particle, and electron beams in hafnium dioxide films
(2009) [Artículo de periódico]The electronic stopping power, S, of HfO₂ films for proton and alpha particle beams has been measured and calculated. The experimental data have been obtained by the Rutherford backscattering technique and cover the range ... -
Experimental and theoretical study of the energy loss of Be and B ions in Zn
(2009) [Artículo de periódico]Energy-loss measurements and theoretical calculations for Be and B ions in Zn are presented. The experimental ion energies range from 40 keV/u to 1 MeV/u, which includes the energy-loss maximum and covers a lack of ... -
Experimental and theoretical study of the energy loss of C and O in Zn
(2011) [Artículo de periódico]We present a combined experimental-theoretical study of the energy loss of C and O ions in Zn in the energy range 50–1000 keV/amu. This contribution has a double purpose, experimental and theoretical. On the experimental ... -
Introducing electron capture into the unitary-convolution-approximation energy-loss theory at low velocities
(2011) [Artículo de periódico]Recent developments in the theoretical treatment of electronic energy losses of bare and screened ions in gases are presented. Specifically, the unitary-convolution-approximation (UCA) stopping-power model has proven its ...
