The method of complex-coordinate rotation is used to calculate shape resonances lying above the [ital N]=5 hydrogen threshold in [ital e][sup [minus]-]H scattering. We report resonance parameters for [sup 3][ital P][sup [ital o]], [sup 1][ital D][sup [ital e]], [sup 3][ital F][sup [ital o]], [sup 1][ital F][sup [ital e]], [sup 1][ital G][sup [ital e]], [sup 3][ital G][sup [ital e]], [sup 1][ital G][sup [ital o]], [sup 3][ital G][sup [ital o]], [sup 1][ital H][sup [ital o]], [sup 3][ital H][sup [ital e]], [sup 1][ital I][sup [ital e]], [sup 3][ital I][sup [ital o]], [sup 1][ital K][sup [ital o]], and [sup 3][ital K][sup [ital e]] states for a total of 19 shape resonances. Resonance energies and widths are obtained by employing up to 1642 terms of wave functions constructed by the products of Slater-type orbitals. The shape resonances are the top portions of the supermultiplet structures for doubly excited intrashell states of H[sup [minus]] associated with the [ital N]=5 hydrogen threshold. For completeness, we also list the doubly excited Feshbach resonances obtained in previous complex-rotation calculations. Together with the present results for shape resonances, all the doubly excited intrashell states associated with the [ital N]=5 hydrogen threshold are now accounted for.
