A contributor to international nomenclature recommendations for X-ray spectroscopy. The system relates line names to electronic energy levels instead of requiring a separate historical label for every transition, making complicated spectra easier to describe consistently.^[ref]

A scientific contributor to IUPAC recommendations for labeling X-ray emission lines and absorption edges. Connecting a spectral label with an energy-level designation makes the notation applicable to different transitions, improving the comparability of spectroscopic descriptions.^[ref]

A contributor to a standardized notation for X-ray spectroscopy. Naming a line through the electronic levels involved reduces reliance on historical labels. The resulting nomenclature gives experimentalists a consistent way to communicate which atomic transition a measured feature represents.^[ref]

A scientific contributor to IUPAC recommendations that standardize names for X-ray spectroscopy. The proposed notation identifies emission lines and absorption edges through their underlying energy-level designations, making the physical transition easier to compare across measurements and publications.^[ref]

A physics educator whose joint classroom experiment uses a cloud chamber to connect particle detection with observable condensation. The chamber’s temperature gradient creates vapor that condenses along ionized tracks. Illumination at a low angle reveals those tracks, letting students investigate naturally occurring cosmic rays with simple optical and thermal equipment.^[ref]

A physics educator whose work with Paloma Alameda-Meléndez makes particle detection accessible through a homemade diffusion cloud chamber. An alcohol reservoir above a dry-ice-cooled base creates a sensitive vapor layer. Ionization along a passing particle’s path triggers droplets, turning an invisible trajectory into a visible track without a particle accelerator.^[ref]

A physics educator whose 1912 book addressed the organization and purpose of physics teaching. In the author’s preface he rejected a rigid sequence of prescribed lessons: a teacher must think independently and adapt the work to the local setting. The book documents an attempt to make instruction in physics serve active scientific reasoning rather than depend on a universal classroom recipe.^[ref]

A contributor to the NIST charged-particle stopping and range databases. Their energy-dependent tables make calculated electron stopping power and ion energy losses reusable across materials. The tabulated ranges summarize slowing behavior while keeping the particle type and initial energy explicit.^[ref]

A researcher whose joint reference-data work provides charged-particle stopping power and continuous slowing-down approximation range. Integrating the inverse energy-loss rate estimates a path length, giving users a consistent way to connect local energy loss with an overall slowing distance.^[ref]

A contributor to NIST tables for electrons, protons and helium ions. The data connect initial particle energy with stopping power in different materials. Comparing materials and energies helps predict how much energy a charged particle deposits along its passage.^[ref]

A researcher whose joint NIST reference work tabulates stopping power and particle ranges. These quantities describe how charged particles lose energy in matter and how far they travel while slowing. The tables turn microscopic interaction calculations into inputs for detector and radiation-transport estimates.^[ref]

A scientific teaching contributor credited with the initial work used for an IAEA slide set on X-ray production. The shared material explains how tube operating conditions and filtration change the radiation output, helping distinguish the amount of radiation from the distribution of photon energies.^[ref]
