Measurement of cross sections for charge pickup by $$^{\textbf {{84}}}\textbf {Kr}$$ on Al, C and $$\textbf{CH}_{{\textbf{2}}}$$ targets at 400 MeV/u

The nuclear charge pickup cross sections of $$^{84}\hbox {Kr}$$ on $$\hbox {CH}_{{2}}$$, C, and Al targets are investigated using CR-39 nuclear track detector at the highest energy of 395 MeV/u. The cross sections for H are calculated from those measured on C and $$\hbox {CH}_{{2}}$$ targets. The dependence of the charge pickup cross section on target mass is studied.
