Photoelectron data are reported for the first measurement of even-parity hollow lithium states produced by triple photoexcitation of laser-excited lithium atoms. Calculations using the {ital R}-matrix approximation of the energy of these states and partial photoionization cross sections are also reported. Experiment and theory are in excellent agreement on a relative scale. {copyright} {ital 1996 The American Physical Society.}
