    Kinetic energy measurements of ions emitted from alkali halides and their mixtures in 252Cf plasma desorption mass spectrometry
    (University of Peradeniya. Peradeniya, 1997) Abeywarna, U.K.; Zubarev, R.A.; Hakansson, P.; Ariyaratne, T.R.
    Kinetic energy measurements of both positive and negative ions emitted from several alkali halides and their mixtures are reported. The measurements were conducted using the energy cut-off property of the ion mirror of a reflector type 252Cf plasma desorption mass spectrometer. The results obtained indicate that some fraction of the desorbed ions emitted under 252Cf bombardment have a kinetic energy deficit compared to die ions which gain full kinetic energy during the acceleration-region. The initial kinetic energy of a particular ion was found to be rather independent upon the sample composition.
