A recent article in Nature Materials describes how researchers used X-ray scattering during a process called molecular beam epitaxy (MBE) to observe the behavior of atoms as a type of material known as layered oxides were being formed.
Scientists guessed that positronium atoms, being twice as heavy as an electron and electrically neutral, would have very different scattering rates.
Most light waves, however, are scattered incoherently, that is the wave patterns of the outgoing waves are no longer directly in relation to the incoming waves as the light is reflected from the atoms it touches as fluorescent light.
The particles did not scatter as much as expected, indicating they were hitting an unexpectedly small number of hydrogen atoms.
When a sample is excited by a laser pulse, most of the photons are scattered elastically, i.e., at the same frequency as the incident photons, by the molecules or atoms in the material.
But if the material's atomic structure is more random — with some atoms here, and a whole bunch over there, as is the case in many industrially manufactured alloys — then the electron waves scatter and reflect in highly complicated ways that can lead the waves to disappear altogether.
As temperature increases, the atoms vibrate more, and increasing the scattering of bounced electrons.
Even when colder atoms were placed in the trap, they would boil out of the trap in a matter of a few thousandths of a second as a result of the ever present photon scattering.
The white dots making up squares arrayed 45 - degrees to the x / y - axis are selenium (Se) atoms, while the defects — missing Fe atoms in the Fe plane, about a quarter of a nanometer below the Se surface — show up as butterfly - shaped perturbations produced by quantum interference of electrons scattering from the defects.
Particularly elusive has been what's known as coherent elastic neutrino - nucleus scattering, which occurs when a neutrino bumps off the nucleus of an atom.
