Simple method for identifying doubly ionized uranium (U III) produced in a hollow-cathode discharge

Area of Science:

• Atomic Physics
• Spectroscopy
• Uranium Chemistry

Background:

• Uranium (U) is a key element in nuclear applications.
• Understanding its spectral properties is crucial for diagnostics and analysis.
• The spectrum of doubly ionized uranium (U III) is complex and challenging to identify.

Purpose of the Study:

• To investigate the spectral properties of U III.
• To explore the influence of buffer gas type and pressure on U III emission.
• To develop a practical method for U III spectral identification.

Main Methods:

• Emission spectroscopy was employed.
• A hollow-cathode discharge vapor generator was used.
• Studies were conducted using pure fill gases (He, Ne, Ar, Kr, Xe) at varying pressures.

Main Results:

• Spectral intensity of U III increased with the ionization potential of the buffer gas.
• Helium showed an exception to this trend.
• Preliminary data suggest a method for positive U III identification.

Conclusions:

• Buffer gas properties significantly influence U III spectral emission.
• A novel, practical method for identifying U III spectra is proposed based on these findings.
• Further research is warranted to refine the U III identification technique.
