The electronic stopping cross sections in boron for atomic projectiles with Z 11 have been determined in the energy interval 15 to 140 keV. Reasonable agreement is found with theory, however the previously observed periodic dependence of SE on the atomic number of the project i le is also evident. Results for the relative straggling in energy loss are reported for hydrogen projectiles in boron,...
