A study on quantum mechanical approach for C60 diffraction analysis

Diffraction phenomena of large molecules had been demonstrated in many experiments, and these experiments were explained by many theoretical works. In this paper, we presented a detailed theoretical treatment of the single and double-slit diffraction of C60 with quantum theory approach, and we paid close attention to the diffraction experiment of C60 carried out by Zeilinger et al. in 1999. In double-slit diffraction, we further considered the decoherence effect, and found the theoretical results were in good accordance with experimental data.
