    • Low-mass secondary-ion ejection from molecular solids by mev heavy ions : radial velocity distributions 

      Papaleo, Ricardo Meurer; Demirev, P.; Eriksson, J.; Hakansson, P.; Sundqvist, B.U.R. (1996) [Artigo de periódico]
      Secondary ions sputtered in individual MeV ion impacts are analyzed in a high resolution time-of-flight mass spectrometer. The initial radial velocity distributions of low mass (up to m/z≈300 u) positive and negative ...

    • Measurement of MeV ion track structure in an organic solid 

      Papaleo, Ricardo Meurer; Demirev, P.; Eriksson, J.; Hakansson, P.; Sundqvist, B.U.R.; Johnson, R.E. (1996) [Artigo de periódico]
      Radial velocities and effective ejection radii of hydrocarbon secondary ions sputtered electronically from polymer films have been experimentally determined. Using these data, the radial profiles of the energy and momentum ...
