Study On Charge Pick-up Reaction Of Heavy Ions With Intermediate And High Energy

Based on the analysis of the dependence of charge pick-up cross sections of high energy heavy ions in different energy regions on the projectile nuclear mass,target nuclear mass and energy of projectiles,the charge pick-up cross sections of⁵⁶Fe with the highest energy of 497 A MeV and ⁸⁴Kr with the highest energy of 395 A MeV on Al,C and CH₂targets have been studied by CR-39 nuclear detector,respectively,the charge pick-up cross sections of ¹²C with the highest energy of 398A MeV on C,CH₂,AL,Cu and Pb targets are studied.For the charge pick-up cross section of ⁵⁶Fe with the highest energy of 497 A MeV on Al,C and CH₂targets,it was found that in the energy we studied,the cross section of charge pick-up reaction depends on the mass of target nucleus A_T,and the cross section increases with the increase of A_T.By fitting the measured data with the functions (?),the strong dependence on the A_T(b31.0)is obtained,which is different from that observed in the heavier projectile with higher beam energy.For the charge pick-up cross section of ⁸⁴Kr with the highest energy of 395 A MeV on Al,C and CH₂targets,it was found that in the energy we studied,the cross section of charge pick-up reaction depends on the mass of target nucleus A_T,and the cross section increases with the increase of A_T.By fitting the measured data with the functions (?),the strong dependence on the A_T(b31.0)is obtained,which is different from that observed in the heavier projectile with higher beam energy.For the charge pick-up cross section of ¹²C on C,CH₂,Al,Cu,Pb targetswith the highest energy of 398 A MeV,it was found that the cross section of charge pick-up reaction depends on the A_T,and the cross section increases with the increasing A_T.By fitting the experimental results with the power functions (?)and the linear function (?),the linear function relationship between the charge pickup reaction cross section and the target mass can better simulate our data.
