Abstract

ABSTRACT: Rate coefficients for dissociative recombination and state-to-state rotational transitions of the D$_{2}^{+}$ ion induced by collisions with very low-energy electrons have been reported following our previous studies on HD + and H$_{2}^{+}$ . The same molecular structure data sets, excitations ($N_{i}^{+} \rightarrow$ $N_{f}^{+}=N_{i}^{+}+2$ for $N_{i}^{+}=0$ to 10) and de-excitations ($N_{i}^{+}\rightarrow N_{f}^{+}=N_{i}^{+}-2$, for $N_{i}^{+}=2$ to 10) were used for collision energies ranging from 0.01 meV to 0.3 eV. Isotopic effects for dissociative recombination and rotational transitions of the vibrationally relaxed targets are presented.
