ROSE makes it easy to build and train a scattering emulator. ROSE enables aspiring graduate students and long-suffering postdocs to emulate nuclear scattering observables with optical potentials, trading negligible amounts of accuracy for orders-of-magnitude gains in speed.
For any bug reports or feature requests, please make use of the Github issues tab on the repository. We also welcome all pull requests for software, documentation, and user-contributed tutorials!
ROSE is hosted at pypi.org/project/nuclear-rose/. To install as a user, run the following
pip install nuclear-rose.
To install as a developer, clone the repository and run
pip install -e .
from within the project root directory.
To emulate an interaction, you will make an Interaction class, or something similar. Then you will typically make a ScatteringAmplitudeEmulator, which will train an emulator to emulate elastic cross sections.
For a full set of examples walking through emulation and calibration, check the tutorials directory.
You can also check out the documentation page.
You could even check the other BAND softwares and start combining them to write all your Bayesian papers!
