Isotopic and velocity distributions of {sub 83}Bi produced in charge-pickup reactions of {sub 82}{sup 208}Pb at 1A GeV

Isotopically resolved cross sections and velocity distributions have been measured in charge-pickup reactions of 1A GeV {sup 208}Pb with proton, deuterium, and titanium targets. The total and partial charge-pickup cross sections in the reactions {sup 208}Pb+{sup 1}H and {sup 208}Pb+{sup 2}H are measured to be the same within the limits of the error bars. A weak increase in the total charge-pickup cross section is seen in the reaction of {sup 208}Pb with the titanium target. The measured velocity distributions show different contributions--quasielastic scattering and {delta}-resonance excitation--to the charge-pickup production. Data on total and partial charge-pickup cross sections from these three reactions are compared with other existing data and also with model calculations based on the coupling of different intranuclear cascade codes and an evaporation code.
