Charge-changing contribution to energy loss of 32 MeV 3He+ in the charge state non-equilibrium region☆

Abstract Energy losses of 32 MeV 3 He ions by carbon foils were measured in the charge state non-equilibrium region. The mean energy losses exhibited an abrupt change as a functiion of the foil thickness around 40–50 μg/cm 2 . This behavior is quantitatively explained by considering the contribution from charge-changing collisions.
