TkN

[](icons/TkN.png)

Toolkit for Nuclei (TkN) is a C++ library providing easy and fast access to a large variety of nuclear data measurements. It allows, for example, access to ground-state properties, excited level energies, and decay characteristics.

TkN can be linked with ROOT, allowing you to explore the TkN database interactively in the ROOT prompt. It can also be compiled without any dependencies for lighter integration in simulation codes or theoretical nuclear models.

The source code is available on GitLab.

Projects using TkN

The Cubix spectra viewer

Cubix is a graphical interface dedicated to gamma-ray spectroscopy analysis. It provides a list of utilities for 1D-2D-3D gamma analysis (calibration, fits, background estimation, coincidence analysis, etc.) and allows interaction with the TkN database to show known transitions on a spectrum, or to find which nucleus can correspond to an observed transition coincidence.
