Abel transform analysis of ion storage ring imaging data.

Area of Science:

• Atomic and Molecular Physics
• Chemical Physics
• Plasma Physics

Background:

• Dissociative recombination is a key process in molecular plasmas and astrophysics.
• Analyzing product distributions provides insights into molecular dynamics and fragmentation pathways.
• High-resolution experiments at ion storage rings generate complex datasets requiring advanced analysis.

Purpose of the Study:
