The cross sections for the photodetachment from the second bound state of the negative hydrogen ion, H{sup {minus}}(2{ital p}{sup 2} {sup 3}{ital P}{sup {ital e}}), for photon energies above the H({ital n}=2) threshold are calculated using a hyperspherical close-coupling method. This state is parity forbidden to autoionize into H({ital n}=1)+{ital e} and has an extremely small binding energy of 0.01 eV. The results for low photon energies agree with earlier calculations. For energies near the {ital H}({ital n}=3) threshold, two shape resonances are found in addition to many Feshbach resonances. These resonances are identified by examining adiabatic hyperspherical potential-energy curves.
