We investigate the temporal evolution of molecular frame angular distributions of Auger electrons emitted during ultrafast dissociation of HCl following a resonant single-photon excitation. The electron emission pattern changes its shape from that of a molecular σ orbital to that of an atomic p state as the system evolves from a molecule into two separated atoms.
我们研究了在共振单光子激发后，HCl超快解离过程中发射的俄歇电子分子框架角分布的时间演化。随着系统从分子演变成两个分离的原子，电子发射模式的形状从分子σ轨道的形状变为原子p态的形状。
