On inverse scattering for the multidimensional relativistic Newton equation at high energies [PDF]

, 2006
Consider the Newton equation in the relativistic case (that is the Newton-Einstein equation) $$\eqalign{\dot p = F(x),& F(x)=-\nabla V(x),\cr p={\dot x \over \sqrt{1-{|\dot x|^2 \over c^2}}},& \dot p={dp\over dt}, \dot x={dx\over dt}, x\in C^1(\R,\R^d),}\

Geant4 simulations of soft proton scattering in X-ray optics. A tentative validation using laboratory measurements [PDF]

, 2017
Low energy protons (< 300 keV) can enter the field of view of X-ray space telescopes, scatter at small incident angles, and deposit energy on the detector, causing intense background flares at the focal plane or in the most extreme cases, damaging the X ...

X-ray Scattered Halo around IGR J17544-2619 [PDF]

The Astrophysical Journal, Volume 785, Issue 1, article id. 23, 10 pp. (2014), 2014
X-ray photons coming from an X-ray point source not only arrive at the detector directly, but also can be strongly forward-scattered by the interstellar dust along the line of sight (LOS), leading to a detectable diffuse halo around the X-ray point source.
