Fine Structure Relaxation Rate Coefficients for Ion Collisions with Hydrogen

Relaxation rate coefficients for fine-structure transitions of Ne+, Ne2+, Ar+, and Ar2+ in collisions with atomic hydrogen are provided. The data covers a temperature range up to 10,000 K. The dataset was contributed by author J. F. Babb and is available via the paperswithcode platform.

Use Cases

• Modeling interstellar medium cooling based on ion-neutral collision rates.
• Simulating plasma kinetics using temperature-dependent fine-structure transition coefficients.
• Calibrating theoretical collision cross-section calculations with empirical rate data.

Strengths

• Data covers a specific temperature range up to 10,000 K.
• Focuses on four distinct ion species (Ne+, Ne2+, Ar+, Ar2+) colliding with atomic hydrogen.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
