Cubix is an open source ROOT based graphical interface providing a large number of tools for gamma-ray spectroscopy analysis. It is linked with the TkN library to provide a direct access to nuclear databases like ENSDF, XUNDL or NuDat3.

It allows to:

  • Analyse 1D, 2D, 3D gamma spectra:
    • fit peaks,
    • perform coincidence analysis,
    • estimate backgrounds.
  • Perform angular correlation analysis:
    • plot theoretical distributions,
    • determine transition multipolarity,
    • evaluate mixing ratio.
  • Characterize detectors:
    • energy calibrations,
    • resolution estimation,
    • efficiency measurements.
  • Browse nuclear databases:
    • ENSDF reader to display published values on spectra,
    • coincidence finder
    • nuclear chart browser.
