Effects of anisotropy on the resonant scattering of hydrogen atom from the fullerene C60

Abstract

From a macroscopic point of view, the C60 and the interaction offered by it is considered spherical because of its symmetry. However, the C60 is formed of hexagonal and pentagonal rings of Carbons. Therefore, on a microscopic level, the interaction potential offered in the elastic scattering of projectiles from the C60 is anisotropic. Elastic scattering of Hydrogen atom from the C60 with the interaction taken to be anisotropic is discussed in the present work. The complex radial and angular dependence of H-C60 interaction is calculated using the Density Functional Theory. The scattering resonances are seen to be modified to significant extent in comparison with the isotropic scattering case. However, the parameters of the non-resonant scattering are mostly unaffected due to the anisotropic effects.
