The Bialas-Bzdak model of elastic proton-proton scattering assumes a purely imaginary forward scattering amplitude, which consequently vanishes at the diffractive minima. We extended the model to arbitrarily large real parts in a way that constraints from unitarity are satisfied. The resulting model is able to describe elastic pp scattering not only at the lower ISR energies but also at √ s =7 ...

The sensitivity of nucleon-nucleus elastic scattering observables to the offshell structure of nucleon-nucleon t-matrices, derived from realistic NN potentials, is investigated within the context of a full-folding model based on the impulse approximation. Our study uses recently developed NN potential models, which describe a subset of the NN data base with a χ2 per datum ∼1, which means that t...

We consider the impact of two recent π − p → ηn measurements on the ηN scattering length and ηN branching fractions for the N (1535) and N (1520) resonances within a coupled-channel analysis of πN elastic scattering and ηN production data. The sensitivity of these results to model input is also explored.

We have measured inelastic electron-deuteron, electron-proton, and electron-aluminum cross sections at 10' in the kinematic region between-elastic deuteron scattering and the second resonance region at six beam energies between 9.8 and 21 GeV. The elastic electron-neutron cross section was extracted from the quasi-elastic data at Q2 = 2.5, 4.0, 6.0, 8.0 and 10.0 (GeV/c)'. The ratio of elastic c...

We argue that, in many situations, fits to elastic scattering data that were historically, and frequently still are, considered “good”, are not justifiably so describable. Information about the dynamics of nucleon-nucleus and nucleus-nucleus scattering is lost when elastic scattering phenomenology is insufficiently ambitious. It is argued that in many situations, an alternative approach is appr...

Features of high energy pp and pA elastic scattering at small t Abstract A method of determination of the real part of the elastic scattering amplitude is examined for high energy proton-proton and proton-nuclei elastic scattering at small momentum transfer. The method allows to decrease the number of model assumptions, to obtain the real part in the narrow region of momentum transfer and check...

We discuss two recent topics on heavy-ion quasi-elastic scattering at energies around the Coulomb barrier. The first topic is an application of quasi-elastic scattering at deep-subbarrier energies to extracting the surface diffuseness parameter of the nucleus-nucleus potential. The second topic is a coupled-channels analysis for the quasi-elastic barrier distribution for the 70Zn + 208Pb reacti...

We show that under certain conditions a simple relationship exists between the elastic scattering of a composite halo nucleus and of its core from a stable target. The coupling of the elastic and projectile excitation channels is crucial to the analysis, which is particularly useful when the ratio of the halo to the core mass is small. In the case of Be elastic scattering the cross section rela...

We carry out a relativistic calculation of the cross sections of electron-O and -C quasi-elastic scattering and quasi-free ∆ production and compare with the (e, e) data systematically in the wide energy range of 0.5 – 1.5 GeV. Using the same formalism, we examine the νμ quasi-elastic scattering from O. The model incorporating the nuclear correlation effects agrees better with the electron-nucle...
