“…Similarly, by assigning a unit stopping power value to the selected non-analyte spike and following the guidelines laid down by the average stopping power approach [8,9], an expression for C x in terms of stopping powers [2] can be deduced, giving,…”

By using particle induced prompt photon spectrometry, PIPPS, and spiking both the analyte sample and analyte standard with a common non-analyte element to which a relative deceleration property for 5 MeV protons was ascribed, relative stopping powers/ranges for these target materials could be obtained. This approach circumvents the need to apply to compounds the Bragg-Kleeman rule (which does not take the changes in electronic structure through chemical bonding into consideration). Lithium carbonate, to which an arbitrary relative stopping power/range of unity was ascribed for 5 MeV protons, was chosen as the non-analyte spike to determine fluorine in polymer samples by using pure fluorine compounds as the comparator standards. The method was tested by analysing the standard reference materials SRM 91, 120c and 694.

In this discussion, we first try to define the cases where analysis by irradiation with charged particles requires the use of relatively high energy beams, e.g from a cyclotron or from a Tandem Van de Graaff.It seems that the most important method using high energy charged particles, is activation analysis.We describe the important features of this method, we compare them with those of other methods, and we try to show the important role it plays in two important fields : -The analysis of traces -The elaboration of reference materials, IntroductionIt is well recognized that charged particles

“…The question now arises whether the average stopping power method [9,10] can be applied as successfully, as in the case of the average cross-section method, to eliminate matrix effects in proton induced prompt gamma ray spectrometry when spiking with a non-analyte element is used. In the average stopping power method an average energy, E", is calculated for the specific nuclear reaction in question and E^ is obtained from excitation functions constructed either from thin [9] or thick [10] target Irradiation.…”

“…In the average stopping power method an average energy, E", is calculated for the specific nuclear reaction in question and E^ is obtained from excitation functions constructed either from thin [9] or thick [10] target Irradiation. An average stopping power, S, is now calculated for the target materials at the average energy, E", which is then substituted in the comparator Equation 2 to obtain the desired concentration of analyte element.…”

It is shown that by applying the average stopping power approach in proton induced prompt gamma spectrometry good results can be obtained in elemental or isotopic analyses if the matrix effects are eliminated by spiking with a non-analyte element absent from the sample. An exact knowledge of average energies and its associated average stopping powers is irrelevant and the best results will be obtained when the average energies pertaining to the non-analyte and analyte are dose in value and when the non-analyte spike chosen is such that the mean atomic numbers of sample and spike are also closely related.
