External-beam PIGE for fluorine determination in atmospheric aerosol
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 1998Abstract Air pollution measurements have been performed at Montelupo, a town about 20 km west of Florence, characterised by the presence of a large number of ceramic and glass factories just inside the inhabited area. Both filters collecting aerosols during 24 h and streaker filters with 1-h resolution capability have been analysed, using external ...

Quantitative analysis of Li by PIGE technique
Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2017Abstract In this work, the cross section of the reactions 7Li(p,pγ)7Li (γ – 478 keV) at the proton energy range 2.0–4.2 MeV was measured. The measurements were carried out at the 3 MV Tandem Accelerator at the CTN/IST Laboratory in Lisbon. To validate the obtained results, calculated gamma-ray yields were compared, at several proton energy values ...

Nondestructive analysis of paintings by PIXE and PIGE
Studies in Conservation, 1985AbstractElemental analysis of pigments by particle induced X-ray and gamma-ray emission (PIXE/PIGE) has been developed for application to paintings. Basic features of these methods have been studied. It is shown that simultaneous use of PIXE and PIGE covers the most important region of interest in nondestructive elemental analysis of inorganic pigments.

Ambiguities in PIGE caused by different reactions
AIP Conference Proceedings, 1985On the basis of relative thick target PIGE yield curves determined experimentally the role of different (p,x) reactions exciting a given γ‐transition in a nucleus is treated. It is shown, that the proper selection of bombarding energies can solve the ambiguity caused by possible reactions in the analysis of a matrix.
