spelling Swift charged particles in a degenerate electron gas: An estimation for the charge-sign effect in stoppingNagy, IstvanAldazabal, ÍñigoStopping powerCharge-sign effectRegularizationarXiv:1812.05663v1Motivated by the recently introduced [Phys. Rev. A 94, 042704 (2016)] and already investigated [J. Phys. B: At. Mol. Opt. Phys. 50, 185201 (2017)] new approximate form for the stopping power in terms of scattering phase shifts, here we show analytically that within such a modeling of the observable an exact leading phase shift may contain that information which is completely enough to characterize the asymptotic charge-sign-independent Bethe term (∝Z21) and a charge-sign-dependent (Barkas) term (∝Z31) in the stopping force of a degenerate electron gas for fast projectiles with charge . Our study is based on a spherical potential with velocity-dependent screening as in the above works. The next term in an asymptotic expansion, the Bloch term (∝Z41), measures the difference of the exact and first-order Born treatments with Coulomb potential.This work was supported partly by the Spanish Ministry of Economy and Competitiveness (MINECO: Project FIS2016-76617-P).Peer reviewedElsevierMinisterio de Economía y Competitividad (España)Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202020202020info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Preprintinfo:eu-repo/semantics/submittedVersionhttp://hdl.handle.net/10261/218605reponame:DIGITAL.CSIC.
