A survey is given to show the different steps in a functional multidimensional analyzer design and construction. There are no difficulties in using it either in simple or in complex experiments, although the component number is rather important. The total unit and the standard digit code are described. Input and control of the analyzer can be varied according to the kind of experiment, such as by splitting it to adapt it to experiments of various storage degrees.

La section efficace de diffusion et la repartition angulaire des photons diffuses dans la zone de la resonance geante ont ete etudiees pour l'or, le tantale, l'holmium et l'erbium. Les resultats obtenus sont en accord avec un modele collectif du type Danos Okamoto au voisinage du maximum de la resonance. Le desaccord constate pour la zone d'energie superieure peut etre interprete par l'apparition d'une excitation quadrupolaire.

Relative measurement of the ratio Γ γ/ Γ is made from resonance to resonance with a large liquid scintillator. Results are given for Nd and Pt. Occurrence of fluctuations of the Γ γ values is discussed. The annular crystal spectrometer is used to investigate the possible contribution from direct radiative capture in Au.
