Binary stopping theory for swift heavy ions

WebBinary theory of electronic stopping, developed recently with the aim of quantifying stopping forces on swift heavy ions, has been applied to antiproton stopping. Essential ingredients in the theory are inverse-Bloch and shell corrections. The numerical input consists of the excitation spectrum of the stopping material, characterized by bundled … WebSep 14, 2024 · The Bloch correction is known as the link between Bethe’s quantum theory of the stopping of charged particles in matter and Bohr’s classical theory. Less well-known and underestimated in the literature, is …
