Charge Exchange Nuclear Reactions Induced by a Pion

Excitation of Giant Resonances in Pion Charge-exchange Reactions

Nuclear-structure aspects of nonanalog pion double charge exchange.

ined. t|)j'e consider the nonanalog ground-state to ground-state (T=0 to T=2) transitions on a variety of nuclear targets. The reaction model, which assumes that double charge exchange is driven by a m+p-meson —mediated„633 nucleon interaction, reproduces the energy dependence and shape of the empirical cross section for all the (m+, m ) transitions examined. The magnitude of the cross section ...

Nuclear halo structure from quasielastic charge-exchange reactions

Neutron and proton densities in the nuclear periphery are investigated within (p,n) charge-exchange isobar transitions. For this purpose we have developed parameterfree optical potentials 1) with a detailed treatment of the in-medium tτ part of the effective interaction. Non local coupled-channel Lane equations are solved to obtain the scattering observables. The use of conventional proton and ...

Energy dependence of pion double charge exchange

Pion double charge exchange ~DCX! on nuclear targets has been extensively studied, both experimentally and theoretically, throughout the last two decades. Because at least two nucleons must be involved in the process, the study of DCX is a natural tool for exploring nucleon-nucleon correlations. In the course of these studies at low energies, a prominent peak in the (p,p) cross section in the n...

Single Pion Production in Neutrino Reactions and Estimates for Charge - Exchange Effects

We calculate single pion production by neutrinos in the resonance region. We consider both charged and neutral current reactions on free protons and neutrons. We present differential and total cross sections which can be compared with experiments. Then we use these results to calculate the spectra of the emerging pions including the Pauli suppression factor and rescattering corrections for reac...
