The first half of the book, written by the primary authors, describes the interactions between incident ions and target atoms and introduces five ion beam analysis techniques: backscattering spectrometry, elastic recoil detection, nuclear reaction analysis, particle-induced x-ray emission, and ion channeling.
Using the sensitive analytical technique known as particle-induced X-ray emission, the scientists first found three hairs with much higher iron-to-zinc ratios than hairs from humans, other primates in China, or bears, says Frank E.
