Charge exchange in relativistic heavy ion collisions
Elastic charge-exchange in relativistic heavy ion collisions is responsible for the non-disruptive change of the charge state of the nuclei. We show that it can be reliably calculated within the eikonal approximation for the reaction part. The formalism is applied to the charge-pickup cross sections of 158 GeV/nucleon Pb projectiles on several targets. The relative contributions of pionand rho-...

متن کاملHeavy-ion charge exchange in the eikonal approximation
In high-energy collisions (E,,, > 50 MeV/nucleon) the eikonal approximation provides a transparent description of heavy-ion exchange reactions. The formalism is applied to the reaction ‘3N(‘3C, 13N)13C at 70 MeV/nucleon. The relative contributions of pionand rho-exchange are determined. It is found that heavy-ion reactions are more sensitive to the one-pion exchange component of the interaction...
متن کاملStudies of charge exchange in symmetric ion–ion collisions
We have measured the total cross sections for single charge exchange in He– He, Ne–Ne and Ar–Ar collisions at centre-of-mass energies of 1.8–14.8, 1.8–10.8 and 2.8–7.3 keV, respectively, using an intersecting beam technique. The results for He–He collisions are compared with existing measurements and calculations. For Ne–Ne and Ar–Ar the measured cross sections are compared with results from ne...
متن کاملImpact of Extended Charge Distribution on Energy-Loss Straggling of Heavy Ions
The energy-loss straggling of partially ionized heavy ions is determined by the stochastic fluctuations of the energy loss in atomic collisions remaining in a fixed charge state, (collisional straggling) and by the influence of charge-state fluctuations (charge-exchange straggling) [1, 2]. Besides the charge-changing cross sections the charge-exchange straggling depends critically on the differ...
