The Workshop on "Nuclear Reaction Data for Science and Technology: Materials Analysis" was held at the Abdus Salam International Centre for Theoretical Physics in May 19-30, 2003. It was intended to present an extensive, and up-to-date, overview of the applications of nuclear data to materials analysis and validation. Dedicated lectures were given on prompt-charged particle analysis, particle-induced X-ray spectrometry, nuclear reaction analysis, prompt gamma and neutron activation analyses, ion beams analysis. The physics underlying such analyses, and the determinations of the needed reliable nuclear data, were discussed thoroughly. The Workshop included also basic lectures on material analysis, nuclear models, particle-matter interactions, and presentations of the nuclear data libraries were given. A substantial amount of time was devoted to practical exercises on simulation and nuclear data retrieval. We here include lecture notes on: the physics of charged particle interactions with nuclei; differential cross sections of protons and helions on light nuclei; nuclear reaction analysis; Rutherford backscattering spectrometry; the IAEA Nuclear Data Services.
