使用同步加速器辐射激发，记录了原子氢的巴尔默发射穿过水分子氧 K 边缘的共振。观察到在里德伯共振激发下发射最强。使用核心到里德伯激发分子动力学的定性模型来解释观察结果。该模型通过共振俄歇衰变和随后的解离将核心激发的水分子的量子态与荧光氢原子的状态联系起来。
The Balmer emission from atomic hydrogen has been recorded across the resonances at the oxygen K edge of the water molecule using synchrotron radiation excitation. The emission is observed to be strongest at excitations to Rydberg resonances. The observations are interpreted using a qualitative model for the dynamics of the core-to-Rydberg excited molecule. The model links the quantum state of the core-excited water molecule via resonant Auger decay and subsequent dissociation to the state of the fluorescing hydrogen atom.
