Total electron scattering cross sections from para-benzoquinone in the energy range 1-200 eV

Area of Science:

• Atomic and Molecular Physics
• Chemical Physics
• Materials Science

Background:

• Accurate electron scattering cross sections are crucial for understanding electron transport in materials.
• Previous studies have provided some data for para-benzoquinone, but a comprehensive database is needed for modeling.

Purpose of the Study:

• To experimentally determine total electron scattering cross sections for para-benzoquinone.
• To compile and complement existing data with new calculations for a comprehensive cross section database.
• To evaluate the self-consistency of the data through electron transport simulations.

Main Methods:

• Measurement of electron beam attenuation under magnetic confinement.
• Calculation of elastic and inelastic scattering cross sections.
• Evaluation of systematic errors using an independent atom model and screening corrected additivity rule.
• Simulation of electron transport for data validation.

Main Results:

• Total electron scattering cross sections for para-benzoquinone were obtained for energies between 1 and 200 eV.
• Random uncertainty was within 5%.
• A comprehensive cross section database was compiled, including new elastic and inelastic scattering calculations.

Conclusions:

• The generated dataset is suitable for electron transport modeling of para-benzoquinone.
• The study provides essential cross section data for further research in the field.
• Self-consistency checks confirmed the reliability of the obtained data.
