在被限制在富勒烯中的原子的光致电离中，直接从原子电离的电子部分从笼子反射。然而，价原子电子也可以与它们的直接发射平行地从笼子中射出。反射振幅和副振幅在电子的动量空间中振荡，其频率由它们与直接振幅的路径差决定。由此得到的横截面揭示了傅里叶共轭区域中的限制几何。该频率模式区分了原子发射和富勒烯发射。
In the photoionization of an atom endohedrally confined in a fullerene the electrons directly ionized from the atom partially reflect from the cage. However, the valence atomic electrons can also eject from the cage collaterally with their direct emission. The reflective and the collateral amplitudes oscillate in the electron's momentum space with frequencies determined by their path differences from the direct amplitude. Resulting cross sections reveal the confining geometry in the Fourier conjugate domain. The frequency pattern distinguishes the atomic emission from the fullerene emission.
