Scattering on a Lennard-Jones potential, cross-section computation.
The description is on: https://compphys.go.ro/quantum-scattering/
Some short info: The referred formulae are from the book "Computational Physics" by J M Thijssen, isbn: 9780521833462, https://doi.org/10.1017/CBO9781139171397, the theory is in chapter 2
The parameters and theory and experimental data can be found in "Molecular beam scattering studies of orbiting resonances and the determination of van der Waals potentials for H–Ne, Ar, Kr, and Xe and for H2–Ar, Kr, and Xe", by J. Peter Toennies, Wolfgang Welz, and Günther Wolf, published in The Journal of Chemical Physics 71, 614 (1979), https://doi.org/10.1063/1.438414
The project compiles on Windows with Visual Studio 2026 (the code can be compiled with older versions starting with VS 2015, but it's currently maintained with VS 2026 and C++ 17 or higher).
The program requires the typical VC++ runtime libraries. Additional libraries needed are VTK https://vtk.org/ and wxWidgets https://wxwidgets.org/.
