AbstractAbstract
[en] The equation of state for cold nuclear matter is determined by the effective, density-dependent interaction between bound nucleons at temperature T=0. This interaction can be probed in elastic nucleus-nucleus collisions at various density overlaps which may extend to several times the normal matter density. For this purpose the elastic scattering of 16O ions on 16O has been measured at incident energies from 250 to 1120 MeV with high accuracy. From these data, which sample both diffractive and refractive scattering processes, was extracted the underlying scattering potentials utilizing model-unrestricted analysis methods. These potentials fit very well into the systematics found in light-ion scattering and compare very favorably with microscopic calculations, if these are based on a weak density dependence of the effective NN interaction, resulting in a soft equation of state for cold nuclear matter

AbstractAbstract
[en] We propose to construct and deploy a fine-grained detector in the Fermilab NOvA 2 GeV narrow-band neutrino beam. In this beam, the detector can make unique contributions to the measurement of quasi-elastic scattering, neutral-current elastic scattering, neutral-current π0 production, and enhance the NOvA measurements of electron neutrino appearance. To minimize cost and risks, the proposed detector is a copy of the SciBar detector originally built for the K2K long baseline experiment and used recently in the SciBooNE experiment.

AbstractAbstract
[en] A study is made of deuteron-nucleus elastic and quasi-elastic scattering and the connection between the opaque nucleus model and the Glauber model is pointed out. The contributions to different cross-sections of the collisions in which the nucleus, excited by one of the nucleons of the deuteron, is brought back to the ground state by the other nucleon is analysed. Coherent deuteron disintegration is found to be highly improbable when the target nucleus is heavy and incoherent disintegration accounts for nearly all the deuteron disintegration. Thus a correct comparison between theoretical and experimental data on proton stripping must take the incoherent deuteron disintegration into consideration

AbstractAbstract
[en] The detection of multinucleon transfer channels populated with very low cross-sections allow to study into detail phenomena that are important for a wide class of experiments. Some of the results recently obtained at LNL with the time-of-flight magnetic spectrometer PISOLO are discussed. A comparison between the data and the microscopic calculations performed with the new theoretical model developed by the Copenhagen group are presented

AbstractAbstract
[en] Peripheral (elastic and quasi elastic) collisions between heavy ions are modelled by the scattering at two nuclear potential wells moving on classical trajectories. A time-dependent Schroedinger equation is solved for a small number of active nucleons in these wells. Probabilities obtained from the model for elastic collisions, excitations and transfers of active nucleons are compared with experiment for the 18O + 118Sn reaction at 60MeV. There is a satisfactory agreement for elastic and transfer collisions considering that the model is parameter-free. On the other hand inelastic collisions are underestimated, since the model does not fully account for collective excitations. The model allows predictions of many physical quantities pertaining to heavy-ion collisions (kinetic and angular momentum losses). It can be generalized to the case of deep-inelastic collisions

Le modele presente decrit les collisions peripheriques entre ions lourds comme la diffusion de deux potentiels nucleaires se deplacant sur des trajectoires classiques. On resoud l'equation de Schroedinger dependante du temps pour un nombre restreint de nucleons actifs dans ces potentiels. Les probabilites fournies par le modele pour les collisions elastiques, les excitations et les transferts de nucleons actifs sont comparees avec l'experience pour la reaction 18O+118Sn a 60MeV. L'accord est tres satisfaisant pour la diffusion et les transferts, d'autant plus que le modele ne contient aucun parametre ajustable. En revanche, les collisions inelastiques sont sous-estimees parce que le modele reproduit mal les excitations collectives. Le modele permet de predire de nombreuses quantites physiques intervenant dans les collisions entre ions lourds (pertes en energies cinetique et en moment angulaire). Il se prete a la generalisation au cas des collisions inelastiques profondesOriginal Title

AbstractAbstract
[en] The emergence, as well as the evolution, of the most typical patterns observed in the angular distributions of elastic scattering and surface transfer between heavy-nuclei, is discussed. Starting from the semi-classical approximation, Thom's classification theorem is evoked to further illuminate the connection between these patterns and the collision parameters

AbstractAbstract
[en] A model is proposed to take into account the influence of virtual states on quasielastic incoherent neutron spectra of rotational diffusion. Periodic and hierarchical coupling schemes are combined to find how a distribution of states affects the elastic incoherent structure factor (EISF). The expression for the EISF shows small, but perceptible, departures from the known scattering laws. (orig.)
