# bornagain(1)

simulate and fit neutron and x-ray reflectometry and grazing-incidence small-angle scattering.

## NAME

BornAgain - simulate and fit neutron and x-ray reflectometry and grazing-incidence small-angle scattering.

## SYNOPSIS

**bornagain**

## DESCRIPTION

BornAgain is an open-source research software to simulate and fit neutron and x-ray reflectometry and grazing-incidence small-angle scattering.

Its name, BornAgain, alludes to the central role of the distorted-wave Born approximation in the physical description of the scattering process. The software provides a generic framework for modeling multilayer samples with smooth or rough interfaces and with various types of embedded nanoparticles.

The command **bornagain** launches a graphical user interface that allows to create sample models and to run simulations.

Alternatively, simulations, fits and visualizations can be steered through Python scripts, as described in the online documentation.
