متن کاملPhotoionization of Ce 3+ -ce
Photoionization of the Ce Ce process has been studied using the random phase approximation with exchange method in the energy region 100-150 eV. Comparison of our results with the recent measurement [Müller et al, Phys. Rev. Lett. 101, 133001 (2008)] confirms the suppression effect of the carbon cage in the endohedral fullerene Ce@C+82 photoionization. The reasons for the cause of the confineme...
