Measurement of cross sections for charge pickup by 12C on elemental targets at 400 MeV/n

The nuclear charge pickup cross sections of 12C on CH2, C, Al, Cu, and Pb targets at the highest energy of 398 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 is linearly depended on the target mass. This linear dependence is consistent with the prediction of nuclear peripheral and surface collision of charge pickup.
