Tools for Nuclear Structure and Gamma-Ray Spectroscopy: TkN & Cubix Tutorial, J. Dudouet, IP2I Lyon

This tutorial will introduce TkN and Cubix, two complementary software tools developed to support nuclear-structure studies and gamma-ray spectroscopy analysis. TkN provides a unified interface to nuclear-structure data, allowing users to access information on nuclei, levels, transitions, and evaluated or experimental datasets through command-line tools and a structured database backend. It is designed to reduce the need for ad hoc parsing scripts and to promote more reproducible workflows when working with nuclear data. Cubix is a ROOT-based graphical interface dedicated to gamma-ray spectroscopy analysis. It provides practical tools for spectrum visualization, calibration, peak fitting, and gamma-gamma coincidence analysis, while integrating naturally with nuclear-structure information handled through TkN. The tutorial will focus on practical usage rather than software internals. Participants will learn how to inspect nuclear data from the command line, navigate level and decay information, and use these tools in typical spectroscopy workflows. The goal is to provide a clear entry point for new users while highlighting how TkN and Cubix can improve efficiency, consistency, and reproducibility in everyday nuclear-physics analysis.
