应用薛定谔方程及基尔霍夫定律推导出一种新的关于氦核双缝衍射的强度计算公式,并利用新的衍射强度公式详细研究了氦核的双缝衍射问题.同时,我们也发现在考虑退相干效应时,理论与实验数据符合较好.
Using Schrdinger equation and KCL,we provided a new theoretical descr iption of the diffraction intensity pattern in double-slit experiments with He actom.And we also found the theory calculations and experiment data were consistent when the decoherence effect was considering.
