摘　　要：目前,已有大量的实验和理论对各种粒子的衍射现象进行了深入的研究.我们用量子理论新方法研究C60分子的双缝衍射,从薛定谔方程和基尔霍夫定律出发求得到C60分子的双缝衍射波函数,与实验数据比较我们发现:在考虑C60分子的双缝衍射中退相干机制对衍射图样的影响后所得的结果与实验符合较好.At the present time,the phenomena of many particles diffraction have been studied in many experiments,and these experiments have been explained by some theoretical works.We study the double-slit diffraction by a quantum mechanical approach.Starting from the Schredinger equation and using Kirchhoff＇s law,we obtain the diffraction wave functions for the double-slit.We find that when the effects of decoherece is considered in the C60 double-slit diffraction,the calculation results are in accordance with experimental data.
