“…The three forms for the optical potential models give reasonable agreement with inelastic scattering data of [9] , but the Kisslinger local potential predictions seem to be better at all energies considered in the present work with χ 2 ranging from 5. From the above, we note that the fits reproduced on the basis of the α-cluster model of 12 C nucleus are more reasonable for low energy pions than for pions of higher energies.…”

Elastic and inelastic cross-sections for pion scattering on 12 C at pion kinetic energy ranging from 50 to 260 MeV are computed using three independent methods of π ± -nucleus optical potential, the 3α-particle model of the nucleus, the equivalent local Kisslinger potential and the Laplacian one. Reasonable fits to the measured values are obtained for 12 C without adjusting free parameters. The ability of these methods to account for elastic, inelastic, total and reaction cross-section data are somewhat similar. The Kisslinger-based local potential is the more suitable for describing the elastic and inelastic cross-sections of π ± -nucleus scattering. It seems that the 3α-particle model of 12 C is not useful in the description of pion scattering on 12 C at least in the ∆-resonance region.

Abstract. We have developed a dynamical model for a unified description of the pion-nucleus scattering and photo-and neutrino-induced coherent pion production on nuclei. Our approach is based on a combined use of the Sato-Lee model for the electroweak pion production on a single nucleon and the A-hole model of pion-nucleus scattering. Numerical calculations are carried out for the case of the ^^C target. After testing our model with the use of the pion photo-production data, we confront our predictions of the neutrino-induced coherent pion production reactions with the recent data from K2K and MiniBooNE.

“…The main purpose of such investigations is to understand the mean field encountered by the pion while traversing the target nucleus. This field is usually described in terms of either multiple scattering processes which depend upon the nuclear charge distributions [16][17][18][19][20][21][22][23][24][25] or the complex optical model (OM) potential [26][27][28][29][30]. We will restrict ourselves here to the first one where the projectile undergoes multiple scatterings during its passage through the nucleus.…”

Elastic scattering of positive and/or negative pions (π + and/or π − ) by nuclei has been studied by means of Glauber's multiple scattering theory (GMST). The differential, total and total elastic cross sections using both the full series expansion and the first order correction (called optical limit results, OLA) of the Glauber amplitude, have been calculated. The in-medium πN amplitude (σ e f f . , σ e f f . ) as well as the free πN one (σ f ree , σ f ree ) are invoked into the full series calculations of the Glauber amplitude and our results were compared with the corresponding experimental data. These calculations are carried out for the elastic collisions, π − − 2 He 4 at incident energy 180 MeV, π ± − 3 Li 6 at 240 MeV, π − − 6 C 12 at incident energies 180, 200 and 260 MeV, π + − 8 O 16 at 240 and 270 MeV and π ± − 20 Ca 40 at energy 292.5 MeV. The comparisons reflect that, except around the minima, the full series calculations with the in-medium πN amplitude are better in describing the scattering data than those using the free πN one and both are better than the optical limit results.
