Electron impact ionization cross sections of hydrogen fluoride molecule

Area of Science:

• Atomic and Molecular Physics
• Quantum Chemistry
• Plasma Physics

Background:

• Accurate ionization cross-section data is crucial for understanding plasma processes and material interactions.
• Previous theoretical and experimental data for hydrogen fluoride (HF) ionization is limited, especially for partial and differential cross sections.

Purpose of the Study:

• To determine partial and total ionization cross sections for hydrogen fluoride (HF) from the ionization threshold up to 5 KeV.
• To evaluate partial single and double differential cross sections and their sums at specific electron energies.
• To compare the calculated total ionization cross sections with existing experimental and theoretical data.

Main Methods:

• Utilized a modified Jain-Khare semiempirical approach for calculating ionization cross sections.
• Calculated partial and total ionization cross sections across a broad energy spectrum (ionization threshold to 5 KeV).
• Evaluated differential cross sections at fixed primary electron energies of 100 eV, 200 eV, and 500 eV.

Main Results:

• Presented comprehensive data for partial and total ionization cross sections of HF.
• Calculated differential cross sections where no prior data exists for comparison.
• The calculated total ionization cross sections show good agreement with available experimental and theoretical data, particularly at higher energies.

Conclusions:

• The modified Jain-Khare method provides reliable ionization cross-section data for HF.
• The study fills a gap in the available data for HF ionization cross sections.
• The findings contribute valuable data for applications involving HF in various physical and chemical environments.
