The Selection of Judges and Advocate-General at the Court of Justice of the European Union: The Role of the Panel Established Under Art. 255 TFEU

Ten years after the establishment of the Panel 255 is, therefore, this article makes a first assessment on how this body improved the transparency of the mechanism to select Judges and Advocate-General of the ECJ and the General Court (GC)

Experimental studies of the dissociative recombination of CD

Aims. We determine branching fractions, cross sections and thermal rate constants for the dissociative recombination of CD3CDOD+ and CH3CH2OH$_2^+$ at the low relative kinetic energies encountered in the interstellar medium. Methods. The experiments were carried out by merging an ion and electron beam at the heavy ion storage ring CRYRING, Stockholm, Sweden. Results. Break-up of the CCO structure into three heavy fragments is not found for either of the ions. Instead the CCO structure is retained in 23  ±  3% of the DR reactions of CD3CDOD+ and 7  ±  3% in the DR of CH3CH2OH$_2^+$, whereas rupture into two heavy fragments occurs in 77  ±  3% and 93  ±  3% of the DR events of the respective ions. The measured cross sections were fitted between 1–200 meV yielding the following thermal rate constants and cross-section dependencies on the relative kinetic energy: σ(Ecm [eV] ) = 1.7 ± 0.3 × 10-15(Ecm [eV] ) − 1.23 ± 0.02 cm2 and k(T) = 1.9 ± 0.4 × 10-6(T / 300) − 0.73 ± 0.02 cm3 s-1 for CH3CH2OH$_2^+$ as well as k(T) = 1.1 ± 0.4 × 10-6(T / 300) − 0.74 ± 0.05 cm3 s-1 and σ(Ecm [eV]) = 9.2 ± 4 × 10-16(Ecm [eV] ) − 1.24 ± 0.05 cm2 for CD3CDOD

The dissociative recombination of fluorocarbon ions III: CF+2 and CF+3

International audienceCross sections and branching ratios are presented for the dissociative recombination of the CF+2 and CF+3 ions with electrons. It is found that the channel producing CF + F is dominant for the reaction with CF+2 and the production of CF2 + F is dominant for the reaction with CF+3. The cross sections for these two ions are very similar
