Rcm. Mboweni et al., A PIXE STUDY OF ABNORMAL X-RAYS FROM BINARY FLUORIDES WITH PROTONS INTHE RANGE 0.4-2 MEV, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 85(1-4), 1994, pp. 138-141
Previously reported abnormally high X-ray yields from the fluorides of
some transition metals were confirmed. Using proton beams and beams o
f the molecule-ion H-1(2+), at equivalent proton energies between 400
and 2000 keV the conditions for the production of abnormally high X-ra
y yields were studied for the effect of ion beam energy, beam current,
charge, target thickness and atomic number of the target metal. The e
ffect was probably due to buildup of potential and discharge with the
production of a flux of energetic electrons, with an energy distributi
on peaking above 10 keV.
