TL;DR: In this paper, a momentum-space nucleon-nucleon potential in the OBE frame is presented where part of the phenomenological σ-contribution describing the intermediate range attraction is replaced by the twice-iterated pion-exchange potentials which couple the NN channel with the NΔ(1236) and ΔΔ channels.

TL;DR: In this paper, the authors studied the monopole response in the random phase approximation with nonlinear models for the first time and found that some effective Lagrangians having a bulk compression modulus in the range 280{endash}350 MeV can predict correctly breathing mode energies in medium and heavy nuclei.
Abstract: Isoscalar monopole modes in finite nuclei are studied in the framework of relativistic models currently used in ground state calculations. Response functions in the random phase approximation are calculated with nonlinear models for the first time. It is found that some effective Lagrangians having a bulk compression modulus in the range 280{endash}350 MeV can predict correctly breathing mode energies in medium and heavy nuclei. It is pointed out that the parametrization NL1 (K{sub {infinity}}=211MeV) leads to an anomalous behavior of the monopole response. {copyright} {ital 1997} {ital The American Physical Society}

TL;DR: In this paper, the self-consistent random phase approximation (RPA) response function of infinite Fermi systems is derived from an effective interaction with velocity and density dependence, or equivalently from a local energy density functional.

TL;DR: In this paper, the elastic scattering of mesons was measured with high precision on nuclei with a high precision at the future ENC, EIC, or LHeC facility.
Abstract: We propose to investigate the properties of nuclear matter by measuring the elastic scattering of $J/\ensuremath{\psi}$ on nuclei with a high precision. $J/\ensuremath{\psi}$ mesons are produced from photons emitted in high-energy electron-proton or electron-nucleus scattering in the low-$x$ region. Their scattering on nucleons or nuclei is predominantly mediated by gluonic forces. The measurement could be performed at the future ENC, EIC, or LHeC facility.

TL;DR: In this paper, the angular and energy distributions of knock-cut nucleons are calculated to predict the contribution of such direct collisions to nuclear reactions, and the mean free path is calculated in an aralytical way on the basts of the Fermi gas.
