摘要：

A weak lithium photoexcitation resonance with completely empty K and L shells (KL-hollow lithium) has been discovered using synchrotron radiation and photoion spectroscopy. This Li (3, 3, 3) resonance was observed in the doubly charged Li++ photoion yield spectrum at 175.25 eV and demonstrates electron correlation involving all three electrons in the excitation process. Resonance parameters obtained from the data show excellent agreement with the multiconfiguration Dirac-Fock calculation which assigns 3s(2)3p as the dominant configuration.
