Abstract
4He charge state fractions have been measured in the energy range from 065 to 380 MeV. High beam currents (similar 2 μA) were used and a photoelectric technique was used to normalize the data. The results are in excellent agreement with those obtained by Armstrong et al. in 1965 and confirm the small difference between the charge state fractions measured in carbon and those measured in other foils.Keywords
