average energy loss per unit path length is termed the stopping power [ [S of the material for the ion. A semi-empirical synthesis of experimental values for all ions in all elements is available (SRIM) and a simple treatment is given in (Vickridge and Schmaus 2006). Briefly, S may be deduced from the measured stopping cross-section: 2 1 dE N dx

higher electron shells to stable neutral 205Tl atoms with a half-life of 17.3 million years and a Q value of 50.5 keV, bare 205 Tl81+ (or H-like 205 80+) ions can decay to almost 100% by b decay to the first excited state of 205Pb81+ at E*=2.3 keV, where the generated electron will be captured into the K shell (5). 3.
