STOPPING POWER OF ELEMENTS Z=20 THROUGH Z=30 FOR 5-12-MEV PROTONS AND DEUTERONS

The stopping power for 5-12-MeV protons and deuterons of Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, and Zn has been measured. For most of the materials, the accuracy is 0.3%. For Ca, Sc, Cr, and Mn, which were rather difficult to handle, the results are somewhat less accurate. The results have been compared with published experimental data and with semiempirical tables by Barkas and Berger, by Bichsel, by Janni, by Serre, and by Williamson et al. Most of these are in agreement with our results within their stated accuracies. © 1968 The American Physical Society.
