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.PhysicsKinetic energy measurementsAlkali halides ions252Cf plasma desorption mass spectrometryIon physicsA
