	Threshold photodetachment of negative hydrogen ions stored in a Penning trap has been studied. The electron affinity of hydrogen is determined to 6082.8(7) cm<sup>&minus;1</sup> in good agreement with previous experiments. The Wigner law has been found to be valid in a region of 400 cm<sup>&minus;1</sup> above the threshold.</p>},
