| 摘 要： | Charge state distribution of 0.8MeV/u uranium ions after transmission through a thin carbon foil has been studied. It is observed that the charge state distribution is equilibrated after the uranium ions have passed through a 15μg/cm^2 carbon foil. The equilibrated average charge state is 33.72 and the charge equilibration time of uranium ions in carbon foil is less than 5.4fs.

| Abstract: | Charge state distribution of 0.8MeV/u uranium ions after
transmission through a thin carbon foil has been studied. It is
observed that the charge state distribution is equilibrated after
the uranium ions have passed through a 15 $\mu $g/cm$^{2}$ carbon
foil. The equilibrated average charge state is 33.72 and the charge
equilibration time of uranium ions in carbon foil is less than
5.4fs. |
