Dissociative recombination and rotational transitions of D${}_2^{+}$ in collisions with slow electrons

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${}_2^{+}$ [9,10]. The same molecular structure data sets, excitations ($N_i^{+}\to$ $N_f^{+}=N_i^{+}+2$ for $N_i^{+}=0$ to $10$) and de-excitations ($N_i^{+}$ $\to$ $N_f^{+}=N_i^{+}-2$, 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.
