Ionic fragmentation following the core-level photoionization of Sn(CH3)4 has been studied in the photon energy region between 400 and 600 eV by use of monochromatized synchrotron radiation and time-of-flight mass spectrometry. The production of small ionic fragments Sn+, CHm+ (m=0-2), and H+ is strongly enhanced by Sn 3d photoionization above 500 eV. Fragmentation processes yielding such small ions are interpreted as decomposition of the multiply charged ion Sn(CH3)4q+ (q = 3-5) produced by the vacancy cascade via Auger and/or Coster-Kronig transitions following the Sn 3d photoionization.
