[en] The D-T neutron generators used by small research laboratories are characterized by the following performances. Accelerating voltage: 150-400 kV, beam current <=2mA useful long term neutron yield -10¹¹ in 4πsr. The discussion of the potential of neutron generators for research and application is limited to the scope of machine parameters discussed above. The following topics are discussed: nuclear data measurements, microscopic and macroscopic data; uses as analytical tool in geology, environment, agriculture and other fields where they can compete effectively with other analytical techniques; uses as radiation sources for studies in radiobiology and medical applications; miscellaneous. The discussion includes the aspects of cost, maintenance skills required, existence of regional activities, etc. (author)

[en] This detailed analysis of inclusive spectra resulting from the interaction of light particles and light nuclei shows that very successful fits to the spectral shape may be obtained using a linear combination of phase space distributions kinematically allowed in the outgoing channel. The study of the amplitudes of individual phase spaces shows distant behavior with respect to the entrance channel, the bombarding energy and angle of detection. The characteristics that have been determined so far, point toward a process confined to the low incident momenta of the incoming particles where fusion and successive equilibration is achieved before the composite system decays

[en] The effect of geometrical considerations in the detection of flying spectator particles in projectile fragmentation processes is discussed. It is shown that different Fermi momenta have different probabilities of being detected in a detector of finite opening. A comparison of experimental inclusive deuteron spectra from the ( ³He,d) reaction on /sup 59/Co with the spectator particle mechanism, including the corrections for the probabilities of detection of various Fermi momenta, shows that very good agreement can be found for the centroid position, width, and angular dependence of the peak due to the projectile fragmentation

[en] Kβ/Kα measurements for Ti, V, Cr, Fe, Cu, and Zn have been performed for cases of K vacancies created by K-electron capture and x rays. For nuclei with Z < 28, a marked difference in the Kβ/Kα ratios obtained by the two modes has been found

[en] The inclusive alpha particle spectra from the breakup of the ³He + ⁷Li system at E_³He = 42.9 MeV are analyzed in the frame of the nuclear reaction model whose matrix element does not depend on the relative energies of the outgoing particles and is therefore constant. The comparison with a recent analysis of the p + ⁹Be interaction, leading to the same composite system, has shown the correlation of the final-state configuration on the entrance-channel cluster structure. The existence of broad excited states for ⁶Li excitation energies between 19 and 28 MeV is confirmed. (Auth.)

[en] The need to include the phase space factor in the analysis of α breakup spectra according to Fermi's Golden Rule is indicated. The importance of the number of particles present in the final state is exemplified by a model calculation for proton, deuteron, and triton spectra produced by the breakup of 160 MeV alphas on zirconium

[en] A short description is given of the ALICE experiment, dedicated to the study of heavy-ion collisions at the LHC. The design and performance of the main detectors are presented as well as some R and D results. (orig.)

[en] An important part of the experimental programme at the large hadron collider to be built at CERN will be devoted to the study of the phase transition to quark-gluon plasma in heavy-ion collisions. One detector, ALICE is devoted to the measurement of most observables characterizing the system formed in the collisions whilst the two pp experiments, ATLAS and CMS, have capabilities to measure specific signals.
