摘要：
Measurements of the stopping cross sections of Ge, Sn, and Pb for hydrogen and helium projectiles are presented. The projectile velocities range from the Bohr velocity v0 to 2.5v0. Large deviations from available tables of up to 28% were found. The measured ratio of helium and hydrogen stopping powers are compared to available predictions. Even for isoelectronic elements of the same group of the periodic system. no satisfactory agreement can be found.
