We report on a measurement of the photodetachment of the Li{sup {minus}} ion via the Li(4s)+e{sup {minus}}({epsilon}p) channel. The partial photodetachment cross section below the Li(4p) threshold is dominated by resonance structure. The resonance spectrum in this region is compared to the spectrum of the same resonances recently observed in the Li(3s)+e{sup {minus}}({epsilon}p) cross section. The two spectra were found to be mirror images of each other. The parameters for the two resonances obtained in the 3s{epsilon}p measurement were confirmed. In addition, using the 4s{epsilon}p spectrum, we were able to assign parameters to a third resonance. {copyright} {ital 1998} {ital The American Physical Society}
