Elementary composition of the samples
It is useful to have the elementary composition of the scintillator in order to calculate the electron
linear energy transfer and photon-interaction cross-sections.
It is necessary to calculate the scintillator-water sample composition individually, using for example,
the following compositions kindly provided by J. Thomson, Perkin-Elmer (formerly Packard Bioscience).
