Measurement of cross-sections for charge pickup by 12C on elemental targets at 290MeV/n.

The nuclear charge pickup cross-sections of 1 2 C on CH2, C, Al, Cu and Pb targets at the highest energy of 288 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 1 2 C at our studied beam energies seems to exponentially depend on the target mass with the fitting exponent b ∼ 0. 9 , which can be well explained by the peripheral and the surface collisions of the nuclear charge pickup reactions.
