Using the photo-induced L_3 resonance shift in Fe and Ni as time reference fo...

We study the optical-pump induced ultrafast transient change of the X-ray absorption at the L_3 absorption resonances of the transition metals Ni and Fe in Fe_{0.5}Ni_{0.5}...本研究针对Fe₀.₅Ni₀.₅合金中过渡金属镍（Ni）与铁（Fe）的L₃吸收共振峰处，探究光泵浦诱导的X射线吸收超快瞬态变化……
