Abstract
The measured stopping power of polystyrene for 2.2- to 5.9-MeV protons has been analyzed with the Bloch projectile- correction term and a modified low-velocity projectile- term included in the Bethe-Bloch formula. When the full-strength Walske -shell correction was utilized, the mean excitation energy corresponding to the best fit of the measurements was (71.1±1.8) eV. This result was obtained for a value of the free parameter of the low-velocity projectile- effect formalism of 1.90±0.05, whether or not a Walske -shell correction was included.
