Photodetaehment of electrons from some stable negative ions has been measured. Cross sections of about 10-17 cm2, and the following minimal detachment energies were found: H-: 0.776 eV, C-*: < 0.5 eV, CH-: 0.74 eV, C2- : 3.54 eV, C2H- : 3.73 eV, SO-: 1.09 eV, and SO-: 1.0 eV with an accuracy better than + 0.05 eV.
