Ar_Stankov_2022 ~~~~~~~~~~~~~~~~ The presented RKM considers 23 particle species, including electron, the ground state atom, an atomic and molecular ion, four excited molecular states (:math:`\mathrm{Ar^*_2[^3\Sigma_u^+,v=0]}`, :math:`\mathrm{Ar^*_2[^1\Sigma_u^+,v=0]}`, :math:`\mathrm{Ar^*_2[^3\Sigma_u^+,v\gg0]}`, :math:`\mathrm{Ar^*_2[^1\Sigma_u^+,v\gg0]}`) and all individual 1s (:math:`\mathrm{Ar[1s_{5,. .,2}]}`) and 2p (:math:`\mathrm{Ar[2p_{10,...,1}]}`) states. In addition, energetically higher states than the :math:`\mathrm{1s}` and :math:`\mathrm{2p}` excited states are considered in the model as a single lumped state (:math:`\mathrm{Ar^*[hl]}`). All species are involved in 409 collision processes and radiative transitions. The details of the 23-species RKM are given in Stankov *et al.* (*M. Stankov, M. M. Becker, T. Hoder, D. Loffhagen, Plasma Sources Sci. Technol. 31 (12) (2022) 125002*). .. literalinclude:: ../../plasma/Ar_Stankov_2022.json :language: json :linenos: :caption: 23-species_RKM json data
