Helium Atom Scattering
Helium atom scattering (HAS) is a surface analysis technique used in materials science. HAS provides information about the surface structure and lattice dynamics of a material by measuring the diffracted atoms from a monochromatic helium beam incident on the sample.

Famous quotes containing the words atom and/or scattering:
“The flame from the angel’s sword in the garden of Eden has been catalysed into the atom bomb; God’s thunderbolt became blunted, so man’s dunderbolt has become the steel star of destruction.”
—Sean O’Casey (1884–1964)
“A committee is organic rather than mechanical in its nature: it is not a structure but a plant. It takes root and grows, it flowers, wilts, and dies, scattering the seed from which other committees will bloom in their turn.”
—C. Northcote Parkinson (1909–1993)
