Inclusive pion double charge exchange in lightp-shell nuclei

Abstract

We report the results of a series of measurements of the differential cross sections for inclusive pion double charge exchange in 6,7 Li, 9 Be, and 12 C for positive and negative incident pions of energies 120, 180, and 240 MeV. The data are compared with the predictions of an intranuclear cascade model and a model based on two sequential single charge exchange processes.

Nuclear fragmentation and charge-exchange reactions induced by pions in the Δ-resonance region

“…In the past four decades, pion-nucleus collisions at the ∆-resonance energies have been extensively investigated within the meson factories, i.e., the Los Alamos Meson Physics Facility (LAMPF) in New Mexico, United States [11][12][13][14][15]; the Paul Scherrer Institute (PSI) in Villigen, Switzerland [16]; the Tri-University Meson Facility (TRI-UMF) in Vancouver, Canada [17]; and superconducting * Corresponding author: fengzhq@impcas.ac.cn kaon spectrometer (SKS) at KEK 12-GeV PS, Japan [18]. Several theoretical approaches were developed for understanding the pion induced nuclear reactions [19][20][21].…”

Comparative analysis of proton and pion scattering on the isotopes 6,8Не within Glauber theory

“…At the present time, emphasis is placed on an analysis on nuclear many-body problems (manifestation of tensor forces in pion charge-exchange processes [2,3]), the violation of charge symmetry in the 3 H and 3 Не mirror nuclei [4][5][6], the nuclearmatter effect on pions and their resonance states [7][8][9][10], and a comparison of the scattering of different particles (pions, kaons, protons, and electrons) on nuclei [11][12][13][14]. Quark degrees of freedom in pion scattering were taken into account within effective chiral field theory [7,15].…”
