DOI: 10.1103/physrevlett.134.076401
Abstract: We present first-principles theoretical calculations for the electronic stopping power (SP) of both protons and antiprotons in LiF. Our results show the presence of the Barkas effect: a higher stopping for positively charged particles than… read more here.

DOI: 10.1134/s0021364018210154
Abstract: It has been shown that the excitation of autoionization states at collisions of keV ions with a solid is decisive for inelastic energy loss and, correspondingly, the electronic stopping power dE/dx. It has been proposed… read more here.
