Abstract

Photoionization of the Xe atom and Xe@C₆₀ molecule have been studied using the random phase approximation with exchange (RPAE) method. The Xe atom was described by relaxed orbitals including overlap integrals. The C₆₀ fullerene has been represented by an attractive short range spherical well with potential V(r), given by V(r) =  −V₀ for r_i < r < r_o, otherwise V(r) = 0 where r_i and r_o are respectively, the inner and outer radii of the spherical shell. The time independent Schrödinger equation was solved using both regular and irregular solutions and the continuous boundary conditions at r_i and r_o. The results demonstrate improvement to previous calculations for both the Xe atom and Xe@C₆₀ molecule and compare very well with the recent experimental data.
