The dynamical screening factor for is presented. These results are based on our original model and based on the modified framework developed in [S. Lo, A. V. Korol and A. V. Solov’yov Phys. Rev. A 79 063201 (2009)]. In this modified framework, the σ and the π plasmons of the fullerene are taken into account. Due to the finite width of the fullerene, each plasmon splits into two eigenmodes, resulting in there being four peaks in the structure of the modified dynamical screening factor. The photoabsorption cross section of the two model fullerenes used are shown. These give a qualitative description of the fullerene’s photoabsorption cross section. The manifestation of the two modes of the πplasmon in the cross section are also presented. The model photoionization cross section is compared with quantum mechanical calculations [V. Ivanov et al. J. Exp. Theor. Phys 96, 658 (2003)] and to experimental data [A. K. Belyaev et al. Phys. Scr. 80 048121 (2009)].
