Low-energy collisions between electrons and BeD^+
arxiv(2024)
摘要
Multichannel quantum defect theory is applied in the treatment of the
dissociative recombination and vibrational excitation processes for the BeD^+
ion in the twenty four vibrational levels of its ground electronic state
(X ^1Σ^+,v_i^+=0… 23). Three electronic
symmetries of BeD^** states (,
, and ), are considered in
the calculation of cross sections and the corresponding rate coefficients. The
incident electron energy range is 10^-5–2.7 eV and the electron
temperature range is 100–5000 K. The vibrational dependence of these
collisional processes is highlighted. The resulting data are useful in magnetic
confinement fusion edge plasma modelling and spectroscopy, in devices with
beryllium based main chamber materials, such as ITER and JET, and operating
with the deuterium-tritium fuel mix. An extensive rate coefficients database is
presented in graphical form and also by analytic fit functions whose parameters
are tabulated in the supplementary material.
