Photoablösung von Elektronen bei einigen stabilen negativen Ionen

Abstract

Photodetaehment of electrons from some stable negative ions has been measured. Cross sections of about 10 -17 cm 2 , and the following minimal detachment energies were found: H - : 0.776 eV, C -* : < 0.5 eV, CH - : 0.74 eV, C 2 - : 3.54 eV, C 2 H - : 3.73 eV, SO - : 1.09 eV, and SO - : 1.0 eV with an accuracy better than + 0.05 eV.
