Distribution of scattered photons in cone-beam computed tomography (CBCT)
I am using MCGPU to simulate photon transport in cone-beam computed tomography (CBCT). I ran an experiment, where a water cylinder containing spherical objects was irradiated. The simulation software ...

Compton Scattering Angle Distribution, and the Klein-Nishina Model
I have a Geant4 simulation where 662keV photons are going into a detecting volume (Germanium). As expected, when I look at the output of the simulation, these photons undergo Compton scattering and ...

Simulating scattering particles
How do I simulate the motion of an electron in 2D for a classic case of elastic scattering considering a certain electron emitted from a source and colliding with other particles in vacuum using Monte ...

Finding Scattering Angle by solving Integral numerically with Singularities
I was trying to do a computational project from Computational Physics by Steven Koonin. The problem requires us to solve two integrals each of which has singularity at the lower limit and numerically ...

Suitability of FLUKA for Simulation of Backscattered Radiation off an Asteroid
This one's pretty simple. I'm looking at trying to simulate the backscattered radiation coming off of a S-type asteroid shape model due to impinging GCRs and solar particles. Ideally my simulation ...

Converting between $\frac{d \sigma}{d t}$ and $\frac{d \sigma}{d \Omega}$
I'm performing some simulation where I require the integration of a cross section of the form
$$\sigma = \int_{-s}^{0}dt \frac{1}{(t-\mu^2)^2} f(\theta,\phi)$$
where $s$ and $t$ are the usual ...

Coherent intermediate scattering function from simulations
I want to calculate the coherent intermediate scattering function, $S_{\text{coh}} (\mathbf{Q},t)$, from a molecular dynamics trajectory, based on its definition. The definition of the function is:
$$...

Light scattering vs roughness
I've been searching for an answer to this question in professional circles for a while; now I'd like to ask here, to find out why the answer is not there :)
In my optical modelling (computer ...
