Comparison of experimental stopping power data for MeV protons, deutrons and alpha particles

Abstract

Stopping power data for MeV light ions published by groups from Nara University and from Risö are compared. The results of the two groups agree within the stated accuracies for deutrons and alphas, while the Nara results are systematically lower for protons. Based on the failure of the Nara group to obtain the same stopping power for protons and deutrons of the same velocity, and on comparisons with other published data, it is concluded that the Nara proton results are systematically too low. © 1976.
