IT is well known that when light is scattered by an object small compared with the wave-length, the scattered wave is spherically symmetrical. Similarly, in the wave mechanical treatment of the ...

Measuring up: an electron scattering experiment yields a small proton radius. (Courtesy: Jefferson Lab) For nearly a decade the size of the particle that makes up the bulk of the universe’s visible ...

Jefferson Lab experiment E99-114 — the so-called Real Compton Scattering, or RCS, experiment — explores the scattering of few-GeV photons off the proton at large scattering angles, under which ...

Light scattering has long stood as a cornerstone technique in the characterization of particles across a wide range of scientific disciplines. From pharmaceuticals to food production, and from ...
