Measurement of cross-sections for charge pickup by 12C on elemental targets at 290MeV/n
International Journal of Modern Physics E(2021)
Abstract
The nuclear charge pickup cross-sections of [Formula: see text]C on CH2, C, Al, Cu and Pb targets at the highest energy of 288[Formula: see text]MeV/n were investigated using CR-39 nuclear track detector. The cross-section for H was calculated from those measured on C and CH2 targets. The dependence of charge pickup cross-section on target mass was investigated. It was found that the nuclear charge pickup cross-section of [Formula: see text]C at our studied beam energies seems to exponentially depend on the target mass with the fitting exponent [Formula: see text], which can be well explained by the peripheral and the surface collisions of the nuclear charge pickup reactions.
