“…The upper energy limit is determined by the fact that the EKM and EMN chiral potentials are able to describe NN scattering observables up to 300 MeV [17,[19][20][21]. The phenomenological global KD potential was originally constructed for energies up to 200 MeV [10] and it was then extended up to 1 GeV [11]. It can therefore be interesting to test and compare the validity of the predictions Fig.…”

Proton-nucleus elastic scattering: Comparison between phenomenological and microscopic optical potentials

2018

Background: Elastic scattering is a very important process to understand nuclear interactions in finite nuclei. Despite decades of efforts, the goal of reaching a coherent description of this physical process in terms of microscopic forces is still far from being completed.Purpose: In previous papers [1,2] we derived a nonrelativistic theoretical optical potential from nucleon-nucleon chiral potentials at fourth (N 3 LO) and fifth order (N 4 LO). We checked convergence patterns and established theoretical error bands.With this work we study the performances of our optical potential in comparison with those of a successful nonrelativistic phenomenological optical potential in the description of elastic proton scattering data on several isotopic chains at energies around and above 200 MeV.Methods: We use the same framework and the same approximations as in Refs. [1,2], where the nonrelativistic optical potential is derived at the first-order term within the spectator expansion of the multiple scattering theory and adopting the impulse approximation and the optimum factorization approximation. Results:The cross sections and analyzing powers for elastic proton scattering off calcium, nickel, tin, and lead isotopes are presented for several incident proton arXiv:1806.01037v1 [nucl-th] 4 Jun 2018 energies, exploring the range 156 ≤ E ≤ 333 MeV, where experimental data are available. In addition, we provide theoretical predictions for 56 Ni at 400 MeV, which is of interest for the future experiments at EXL. Conclusions:Our results indicate that microscopic optical potentials derived from nucleon-nucleon chiral potentials at N 4 LO can provide reliable predictions for the cross section and the analyzing power both of stable and exotic nuclei, even at energies where the reliability of the chiral expansion starts to be questionable.

Proton and deuteron activation measurements at the NPI and future plans in SPIRAL2/NFS

et al. 2017

Abstract. The proton-and deuteron-induced reactions are of a great interest for the assessment of induced radioactivity of accelerator components, target and beam stoppers as well as isotope production for medicine. In the present work, the deuteron-induced reaction cross sections on zinc were investigated by stacked-foil activation technique with deuteron beam of 20 MeV energy from the cyclotron U-120M of NPI CASŘež. Also the proton activation cross section measurement of iron is presented. The comparison of present results to data of other authors and to predictions of evaluated data libraries is discussed. The investigation shall continue for higher proton and deuteron energy interval 20-35 MeV at SPIRAL2/NFS facility using a charged particle irradiation chamber with pneumatic transport system to measure isotopes and isomers with half-lives in minutes-regions.

Abstract. The proton and deuteron induced reactions are of a great interest for the assessment of induced radioactivity of accelerator components, target and beam stoppers. In order to investigate the important nuclides, we have carried up the irradiation experiments with the variable-energy cyclotron U-120 M of the NPI CASŘež. The production cross sections of the nuclides 179,181,182m,182,183,184m,184,186 Re and 187 W from reaction on natural W were investigated by deuteron beams of 20 MeV energy. A part of preliminary results of deuteron activation of natural Zr is also shown. The stacked-foil technique was utilized. The comparison of present results to data of other authors and to predictions of evaluated data libraries is discussed.
