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 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, 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 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
