• -induced dissociation leading to bare Cr+, are discussed. In addition, doubly charged cations were identified and the ration between doubly and singly charged fragments was determined and compared with previous studies, showing considerable differences. Keywords: chromium hexacarbonyl Cr(CO)6

• metastable and CID ion yield. Ion yield curves of negatively charged fragments formed by dissociative electron attachment to chromium hexacarbonyl, Cr(CO)6. Electron energy dependence for the metastable decay reactions in the FF1 and the FF2, as well as the prompt ion yields for the involved fragment anions

• hexacarbonyl (Cr(CO)6) sample from Sigma-Aldrich with a stated purity of >98% was filled in an external sample container. The sample container was heated to temperatures between 74 °C and 79 °C. The regulation of the electron current to 10 μA set in at an electron energy of about 2 eV. The ions were extracted
