Elastic Scattering Studies of Fullerenes and its Derivatives

The present work explores the low energy elastic electron scattering from fullerenes and its derivatives. We simulate these fullerenes, C₆₀,C₂₄₀ and the nested fullerene C₆₀@C₂₄₀, by using the well established annular square well(ASW) potential [1]. The static ASW model is relatively easy to implement compared to robust molecular-level models [2]. Despite the simplicity, the static ASW model has been successful in unravelling the qualitative features associated with the scattering dynamics of fullerene molecules in the past. The combined system, C₆₀@C₂₄₀, is modeled by summing the two model potentials directly [3]. The focus of the present work is on identifying the differential cross-section details along with the time delays involved in the scattering process both in the resonant and non-resonant regions.
