Abstract

Interactions of low-energy electrons with the FEBID precursor Cr(CO)(6) have been investigated in a crossed electron-molecular beam setup coupled with a double focusing mass spectrometer with reverse geometry. Dissociative electron attachment leads to the formation of a series of anions by the loss of CO ligand units. The bare chromium anion is formed by electron capture at an electron energy of about 9 eV. Metastable decays of Cr(CO)(5)(-) into Cr(CO)(4)(-), Cr(CO)(4)(-) into Cr(CO)(3)(-) and Cr(CO)(3)(-) into Cr(CO)(2)(-) are discussed. Electron-induced dissociation at 70 eV impact energy was found to be in agreement with previous studies. A series of Cr(CO)(n)C+ (0
