    Influence of the Coulomb field on charged particle emission in Ar + Ni reaction at 77 MeV/u

    No full text
    Ar+Ni collisions at 77 MeV/u were studied in the experiment E286 performed at GANIL. An important advantage of this experiment was an application of the neutron detector DEMON for registration of both neutral and charged particles. This feature allows to compare characteristics of neutrons and protons detected by the same detector and gives a possibility to determine the influence of the Coulomb field on the proton emission. Estimation of a charge of the emitting source was performed by comparing energy spectra of neutrons and protons detected under identical experimental conditions. The experimental results were compared with the prediction of the SIMON model [D. Durand, Nucl. Phys. A541, 266 (1992)] and Landau-Vlasov model [Z. Basrak, Ph. Eudes, P. Abgrall, F. Haddad. F. Sébille, Nucl, Phys. A624, 472 (1997)].SCOPUS: cp.pinfo:eu-repo/semantics/publishe

    Nuclear interferometry for two-nucleon systems (experiment E286 at GANIL)

    No full text
    The main points of a new experiment being prepared currently at GANIL are reported. Simultaneous measurement of two-nucleon (nn, pp, np) correlations at small relative velocities will be performed. Special attention is paid to (nn) correlations as free of Coulomb effects. The physical goal of experiment is to find the space-time properties of nucleon emission dynamics in heavy-ion collisions and to clarify some related questions: sequence of particle emission, three-body Coulomb effects, deuteron production mechanism etc.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
