momentum-transfer method
21Helium 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.… …
22Reactionless drive — A reactionless drive (also known by many other names, such as an inertial propulsion engine, reactionless thruster, reactionless engine, bootstrap drive or inertia drive) is a fictional or theorized method of propulsion where thrust is generated… …
23Biological small-angle scattering — Small angle scattering is a fundamental method for structure analysis of materials, including biological materials. Small angle scattering allows one to study the structure of a variety of objects such as solutions of biological macromolecules,… …
24Many-worlds interpretation — The quantum mechanical Schrödinger s cat paradox according to the many worlds interpretation. In this interpretation every event is a branch point; the cat is both alive and dead, even before the box is opened, but the alive and dead cats are in… …
25Spin wave — Spin waves are propagating disturbances in the ordering of magnetic materials. These low lying collective excitations occur in magnetic lattices with continuous symmetry. From the equivalent quasiparticle point of view, spin waves are known as… …

27Round the corner kicking — was invented in the 1940s by Willie Horne, the Barrow, Lancashire, England and Great Britain captain and rugby league player. His distinctive round the corner style of kicking enabled him to kick over 100 goals in the 1945/1946 season and then he …
28Rietveld refinement — is a technique devised by Hugo Rietveld for use in the characterisation of crystalline materials. The neutron and x ray diffraction of powder samples results in a pattern characterised by peaks in intensity at certain positions. The height, width …
29Electron energy loss spectroscopy — In electron energy loss spectroscopy (EELS) a material is exposed to a beam of electrons with a known, narrow range of kinetic energies. Some of the electrons will undergo inelastic scattering, which means that they lose energy and have their… …
30Sputter deposition — is a physical vapor deposition (PVD) method of depositing thin films by sputtering, that is ejecting, material from a target, that is source, which then deposits onto a substrate, such as a silicon wafer. Resputtering is re emission of the… …
