We report on the first observation of resonance structure in the total cross section for the photodetachment of Li{sup {minus}}. The structure arises from the autodetaching decay of doubly excited 1{ital P}{sup {ital o}} states of Li{sup {minus}} that are bound with respect to the 3{ital p} state of the Li atom. Calculations have been performed for both Li{sup {minus}} and H{sup {minus}} to assist in the identification of these resonances. The lowest lying resonance is a symmetrically excited intrashell resonance. Higher lying asymmetrically excited intershell states are observed which converge on the Li(3{ital p}) limit.
