  2. Luminescence dating - Wikipedia

    en.wikipedia.org/wiki/Luminescence_dating

    The natural minerals that are measured are usually either quartz or potassium feldspar sand-sized grains, or unseparated silt-sized grains. There are advantages and disadvantages to using each. For quartz, blue or green excitation wavelengths are normally used and the near ultra-violet emission is measured (Anti-Stokes shift). For potassium ...

  3. Crystallography - Wikipedia

    en.wikipedia.org/wiki/Crystallography

    Other physical properties are also linked to crystallography. For example, the minerals in clay form small, flat, platelike structures. Clay can be easily deformed because the platelike particles can slip along each other in the plane of the plates, yet remain strongly connected in the direction perpendicular to the plates.

  9. Stopping power (particle radiation) - Wikipedia

    en.wikipedia.org/wiki/Stopping_power_(particle...

    In nuclear and materials physics, stopping power is the retarding force acting on charged particles, typically alpha and beta particles, due to interaction with matter, resulting in loss of particle kinetic energy. [1] [2] Stopping power is also interpreted as the rate at which a material absorbs the kinetic energy of a charged particle.
