Determination of fluorine in urine and tap water by laser-excited molecular fluorescence spectrometry in a graphite tube furnace with front-surface illumination

Abstract

Calculations of the coherent production of free pairs and of pair production with electron capture from ultrarelativistic ion-ion collisions are discussed. Theory and experiment are contrasted, with some conjectures on the possibility of new phenomena. 29 refs., 5 figs., 1 tab.
