Stopping-power formula for magnetic monopoles

A stopping-power formula is presented for magnetic monopoles with charge $|g|=\frac{137e}{2}$ and $|g|=137e$. Close- and distant-collision effects are considered and the estimated accuracy in an absolute sense is \ifmmode\pm\else\textpm\fi{}3% for $\ensuremath{\beta}\ensuremath{\gtrsim}0.2$ and $\ensuremath{\gamma}\ensuremath{\lesssim}100$.
