[en] This updated version of the French National Standards is a collection of synopses of all fundamental and derived units realized in BNM laboratories and some external laboratories. The chapter on ionizing radiation contains in particular data on alpha, beta, gamma and X-ray emitters and bibliographies for international comparisons. Measurements of radiation emission flux in a defined solid angle are described for various aqueous solutions of radionuclides as well as problems of x and gamma ray spectrometry, standards of air kerma rate and dose equivalent rates.

[en] Nuclear structure studies are central to both many-body physics and quantum mechanics, and our goal is to seek a description of these many-nucleon systems in terms of a few degrees of freedom and by using simple quantum mechanical models. Particular emphasis is placed on the region 180 <= A <= 210, and on odd-mass nuclei where the unpaired nucleon can be considered as a probe of the core shape (and softness) and of pairing and few nucleon correlations (via the blocking effect) in the core.

[en] Fast continuous separation methods accomplished by combining a gas-jet recoil-transport system with a variety of chemical systems are described. Procedures for the isolation of individual elements from fission product mixtures with the multistage solvent extraction facility SISAK are presented. Thermochromatography in connection with a gas-jet has been studied as a technique for on-line separation of volatile fission halides. Based on chemical reactions in a gas-jet system itself separation procedures for tellurium, selenium and germanium from fission products have been worked out. All the continuous chemical methods can be performed within a few seconds. The application of such procedures to the investigation of nuclides far from the line of β-stability is illustrated by a few examples. (orig.)

[en] Full text: Exotic nuclei beyond the ¹³²Sn double-shell closure are influenced by both the Sn superfluidity and the evolving collectivity only few nucleons away. Toward even more neutron-rich nuclei, especially at intermediate mass number, interplay between single-particle and collective particle-hole excitations compete. In some cases with the extreme addition of neutrons also other effects as the formation of neutron skin [1], stabilization as sub-shell gaps [2], and/or orbital crossings [3] may be expected. The knowledge of nuclear ingredients is especially interesting beyond ¹³²Sn and little is known on how the excitations modes develop with the addition of both protons and neutrons [4-7] and for example systematic prompt and decay lifetime studies can be a very sensitive probe. Recently, we have approached this region of nuclei in several measurements following fission as ²³⁸U on ⁹Be target, within the EURICA project [8-9], n-induced fission on ²³⁵U/²⁴¹Pu targets using prompt-decay spectroscopy within the EXILL/FATIMA campaigns [10-11], as well as in decay spectroscopy at LOHENGRIN. Examples from these studies on several nuclei in the region will be presented together with the possible interpretation of the new data.
