  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$_{2}^{+}$ [9,10]. 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.
