AbstractAbstract
[en] Inclusive cross-sections for the production of 3He and 4He isotopes in α+α collisions at 218 MeV have been measured, using a semiconductor telescope. The significance of these measurements for theories of galactic cosmic-ray propagation is discussed

AbstractAbstract
[en] Various light- and medium-mass nuclei have been bombarded with 150-, 230-, 600-, and 960-MeV protons. Prompt γ rays were measured with a Ge(Li) detector. A large number of lines in the γ-energy spectra correspond to the de-excitation for the first levels of 4n nuclei (N=Z even). The dependence of this effect on the incident energy and the mass of the target is studied. The data are compared with recent pion-bombardment results

AbstractAbstract
[en] Prompt γ rays emitted in the interaction of high energy protons with nuclei have been detected. The single and multiple α removal which appears as a prominent feature of γ spectra is studied versus energy variation from 150 to 960MeV and versus target atomic mass from 14 to 56. In the case of 16O, Doppler broadening of γ rays from the two 14N first low-lying states indicates a direct reaction mechanism

On a detecte les γ prompts emis dans l'interaction des protons de haute energie avec des noyaux. L'enlevement d'une ou plusieurs particules alpha qui apparait comme le trait essentiel des spectres γ est etudie en fonction de l'energie entre 150 et 960MeV et en fonction de la masse atomique de la cible entre 14 et 56. Dans le cas de 16O, l'elargissement Doppler des raies γ des deux premiers niveaux de 14N indique un mecanisme de reaction directeOriginal Title

AbstractAbstract
[en] γ rays from nuclei bombarded by high energy protons (from 100 MeV to 1 GeV) lead to mass distributions of stable nuclei where 4n-nuclei are the most abundant. With calcium an energy dependence is found. A few evidence for direct or semi-direct processes are reported

AbstractAbstract
[en] Mean multiplicities of π+ and π- in 4He collisions with C, Cu, and Pb at 200, 600, and 800 MeV/u, and with C and Pb at 400 MeV/u have been measured using the large solid angle detector Diogene. The dependence of pion multiplicity of projectile incident energy, target mass and proton multiplicity is studied in comparison with intra-nuclear cascade predictions. The discrepancy between experimental results and theory is pointed out and discussed. (orig.)
