Abstract

In this paper, we have studied the double-slit interference experiment phenomena of the large molecule \({C_{60}}\) with quantum theory approach. We calculate the double-slit wave functions of \({C_{60}}\) molecule by the Schrödinger equation, and calculate the diffraction wave function behind the slits with the Feynman path integral quantum theory, and then give the relation between the interference intensity and interference pattern position. On this basis, we compare the calculation results with the double-slit interference experiments of \({C_{60}}\), which are in accordance with the experimental data, which shows that the matter-wave interference is a quantum phenomenon, it should be studied by the quantum theory method, and the decoherence effect should be considered.
