Kinetic Energy Release for Metastable Fullerene Ions
Abstract
Kinetic energy release distributions for spontaneous (metastable) decay of fullerene ions, Cnz+, have been determined for parent sizes n = 58, 60, and 70, and charge states z = 1, 2, 3, and 4. Extensive numerical modeling has been applied to verify that the shapes of fragment ion peaks in our mass-analyzed ion kinetic energy (MIKE) spectra are not affected by discrimination, making it possible to derive the center-of-mass total kinetic energy release distributions directly from the spectra. Measurements involving C3H8+ and C3H7+ ions confirm the accuracy of the approach.
