The interaction of CF 3 + ions with a stainless steel surface covered with hydrocarbons has been studied with a recently constructed BESTOF tandem mass spectrometer as a function of the collision energy from about 0 up to 60 eV. Whereas the efficient

Surface-induced decomposition of benzene molecular ions (impact energy range 19–30 eV) and hydrogen atom abstraction from surface adsorbates leading to the production of a protonated benzene ion, were investigated using two different types of scatt

Relative activation energies for dissociation of fullerene ions Cnz+ into Cn−2z+ + C2 have been determined for z = 1 and 2, covering the size range 52 ≤ n ≤ 70. These data are derived from measured appearance energies of fragment ions, obtained

We have obtained direct mass spectrometric evidence that fullerene ions C60z+ (z=1, 2, or 3) and C58z+(z=1,2) undergo unimolecular dissociation by sequential emission of two C2 units, on a time scale of 10−5 s. Moreover, a comparison of experimenta

Using recently measured accurate relative partial ionization cross section functions for production of the C60 fragment ions C+58 through C+44 by electron impact ionization, we have determined the respective binding energies BE(C+n–C2), with n=58,.
