Trace element concentrations play an important role in grouping and provenance studies of archaeological artifacts. Particle‐inducedX‐ray emission (PIXE) using low energy proton beams (1.5 and 3 MeV) from a tandem particle accelerator was used to analyze the ancient clay potteries collected from an ancient Buddhist site in India. Concentrations of 13 elements, including eight transition elements, were determined. The concentrations of transition elements were used for the grouping study by statistical cluster analysis according to the similar and dissimilar elemental distribution within the samples. Two International Atomic Energy Agency Reference Materials (RMs) were analyzed to validate the PIXE method. Two samples were analyzed by both PIXE and instrumental neutron activation analysis (INAA) as a part of quality assurance. Grouping results were used for preliminary provenance study.

Selected number of anti-diabetic medicinal plant leaves has been characterized by accelerator based particle-induced X-ray emission (PIXE) technique. Validity of the technique was assured by analyzing certified plant reference materials (CRMs). A large number of trace elements like Ti , V , Cr , Mn , Fe , Co , Ni , Cu , Zn , Rb , Sr and Pb are found to be present in these studied leaf samples with variable proportions. The concentrations of elements like K and Ca are quantified in percentage level whereas other elements are found to be in parts per million levels. Among the studied samples, the leaves of Methi are found to be containing maximum amount of trace elements.
