title = "Fragmentation mechanism of highly excited C70 cations in the extreme ultraviolet",
abstract = "The ion yield curves for C70-2n z+ (n = 1-8, z = 2 and 3) produced by photoionization of C70 were measured in the photon energy (hν) range of 25 - 150 eV. The appearance hv values were higher by ca. 34 eV than the thermochemical thresholds for dissociative ionization of C70 leading to C70-2nz+. Evaluation was made on the upper limits of the internal energies of the primary C70 z+ above which C70-2n+2 z+ fragments cannot escape from further dissociating into C70- 2n z++C 2. These critical internal energies agreed well with appearance internal energies of C70 z+ theoretically obtained corresponding to the threshold for the formation of C70-2n z+. The photofragmentation of the parent C70 z+ ions is considered to be governed by the mechanism of internal conversion of their electronically excited states, statistical redistribution of the excess energy among a number of vibrational modes, and sequential ejection of the C2 units.",
