Elastic and inelastic scattering of π mesons on 7Li nuclei

Polarization observables in the elastic scattering of protons on 9Be nuclei

“…To describe the observables in the elastic p- 9 Be scattering the optical model [11][12][13], macroscopic DWIA [10,12,13] and the coupled channel approximation [12] were used. The 2αn model and MDST were used in [14,15] to describe the polarization observables in the elastic p-9 Be scattering at 220 and 1000 MeV. The results obtained in [14,15] are in agreement with experimental data.…”

“…Notice that the 2αn model and MDST was used in [14,15] to describe the polarization observables in the elastic p-9 Be scattering at 220 and 1000 MeV. In [14,15] the ground state 9 Be wave function was presented as an expansion of Gaussians, and the NN amplitude was taken as a sum of central and spin-orbital interaction. The results obtained in [14,15] are in agreement with experimental data.…”

The results obtained in [14,15] are in agreement with experimental data. Unfortunately, in [14,15] only differential cross-section and analyzing power up to θ ∼ 20 • were calculated.…”

“…Notice that the three-particle wave functions of the 9 Be nucleus in the 2αn model with different pair potentials were calculated, for example, in [9]. Number of approaches to investigate the elastic scattering of protons by 9 Be nucleus at intermediate energies were used by many authors (see, for example, [10][11][12][13][14][15] and references therein). To describe the observables in the elastic p- 9 Be scattering the optical model [11][12][13], macroscopic DWIA [10,12,13] and the coupled channel approximation [12] were used.…”
