“…Apparently, only one measurement exists for 14 N + H 2 at the energy of interest [58] and there are no measurements for 19 F + H 2 . We have compared the Northcliffe and Schilling stopping powers with those calculated using srim, casp and mstar (version 3.12) [59] and find ǫ r (N + H)/ǫ r (F + H) = 0.686 (Northcliffe and Schilling), 0.689 (srim), 0.839 (casp), and 0.901 (mstar). The values for ǫ r (N + H) from Northcliffe and Schilling, srim and mstar are consistent with the measured value within its ±15% uncertainty whereas casp predicts a value that is lower by about 27%.…”

The treatment of electronic excitations in atomistic models of radiation damage in metals

“…A further empirical fitting function is then used to determine the state of ionization of the projectile and this provides the basis for a calculation of the effective charge fraction γ from theoretical considerations. Paul and Schinner [69,70] take stopping data for helium as their experimental reference and fit the quantity, Figure 8. A demonstration of how simple scaling relationships (b) can capture much of the behaviour of the electronic stopping power (a) for a variety of projectile and target combinations.…”

On the gas–solid difference in stopping power for low energy ions

“…In recent years, we have been using a statistical analysis program (''Judge'') [16] to investigate the accuracy of various stopping tables and programs, by comparing them to experimental data from our large collection [17], see, e.g. [18].…”
