在本论文中，我们利用时间分辨双光子光电子能谱研究了C60分子激发态的布居和衰变动力学。我们绘制出如何热激发的振动自由度导致的光激发态的瞬态重新分配。这包括超原子分子轨道（SAMO），这是目前非常感兴趣的。测得的寿命与成熟的第一性原理计算一致。
In this joint theoretical and experimental work we investigate the population and decay dynamics of excited states of the C60 molecule by time-resolved two-photon photoemission. We map out how the thermally excited vibrational degrees of freedom lead to a transient redistribution of the photo-excited states. This includes the super-atom molecular orbitals (SAMOs), which are of great interest currently. The measured lifetimes are in line with full-fledged first-principle calculations.
