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{sup ++} photoion yield spectrum at 175.25eV 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{sup 2}3p as the dominant configuration. {copyright} {ital 1997} {ital The American Physical Society}
