Dataset description

In dissociative recombination, an electron is captured by a molecular ion and this is followed by dissociation into neutral atoms. We have here performed MQDT (Multi-channel Quantum Defect Theory) calculations on dissociative recombination of ArH⁺ and NeH⁺ at low collision energies (< 2 eV). The calculated cross sections can be relevant for modelling of chemistry in interstellar space or e.g. divertor fusion plasmas. The data contains calculated total cross section of dissociative recombination of different isotoplogues of ArH⁺ and NeH⁺ in ro-vibrational states (v,j). The files contain two columns: Collision energy (in eV), Cross section (in cm²). The following cross sections are provided: - ³⁶ArH⁺(v=0,j=0): 36ArH_DRcross_v0j0.txt - ³⁸ArH⁺(v=0,j=0): 38ArH_DRcross_v0j0.txt - ⁴⁰ArH⁺(v=0,j=0): 40ArH_DRcross_v0j0.txt - ⁴⁰ArH⁺(v=0,j=1): 40ArH_DRcross_v0j1.txt - ⁴⁰ArH⁺(v=0,j=2): 40ArH_DRcross_v0j2.txt - ⁴⁰ArD⁺(v=0,j=0): 40ArH_DRcross_v0j0.txt - ²⁰NeH⁺(v=0,j=0): 20NeH_DRcross_v0j0.txt - ²⁰NeH⁺(v=0,j=1): 20NeH_DRcross_v0j1.txt - ²⁰NeH⁺(v=0,j=2): 20NeH_DRcross_v0j2.txt - ²⁰NeH⁺(v=0,j=3): 20NeH_DRcross_v0j3.txt - ²⁰NeH⁺(v=0,j=4): 20NeH_DRcross_v0j4.txt - ²⁰NeH⁺(v=0,j=5): 20NeH_DRcross_v0j5.txt - ²⁰NeH⁺(v=0,j=6): 20NeH_DRcross_v0j6.txt - ²⁰NeH⁺(v=0,j=7): 20NeH_DRcross_v0j7.txt - ²⁰NeH⁺(v=0,j=8): 20NeH_DRcross_v0j8.txt - ²⁰NeD⁺(v=0,j=0): 20NeD_DRcross_v0j0.txt

Questions before production use

Practical answers on evaluation, licensing, freshness, versioning and support.

api.store is built and operated by Apitalks s.r.o. Company details and a direct contact path are linked in the footer for vendor checks and procurement review.
Yes. Selected APIs include a free API quota, so your team can validate coverage, freshness, response shape and workflow fit before asking for a production plan.
Often yes, but usage rights depend on the source license and dataset. We surface source, license and update metadata where available, and can help review terms before a production integration.
Maintained APIs include update metadata where available. For production integrations, we can add history, monitoring and push updates so changes are easier to detect and act on.
Production APIs can add SLA, stable identifiers, versioning support, history, push updates and direct support around the data your product or AI workflow depends on.
