Energy-loss-straggling experiments with relativistic heavy ions in solids
Phys. Rev. Lett., 77 :3987 (November 1996)
Abstract:
Energy-loss straggling measurements performed at the high-momentum-resolution magnetic spectrometer FRS with bare and highly charged O-8, Xe-54, (79)AU, and U-92 ions with specific kinetic energies (700-1000) MeV/u are reported. The results are in good agreement with rigorous calculations recently reported by Lindhard and Sorensen and reveal systematic deviations from the well-known relativistic Bohr formula, which was obtained within the framework of the first-order Born approximation.
