Prompt-gamma activation analysis using the k0 approach

Applying the k(0) standardization method to prompt-gamma activation analysis (PGAA) offers similar benefits as in instrumental neutron activation analysis. It has been demonstrated that under constant flux conditions k(0)-factors obtained by normalizing to a titanium comparator, measured separately, yield consistent analytical sensitivity ratios. The ratio method has been generalized by using stoichiometric compounds for the determination of k(0)-factors. Since chlorine forms compounds with essentially every element and it also serves as a detector efficiency standard, k(0) values have been determined relative to chlorine as an internal standard for several analytically important elements in two reactor facilities: the thermal guided beam at the ERR in Budapest and the cold-neutron beams at the NBSR at NIST.
