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 ...
متن کاملNuclear 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 ...
متن کاملEnergy 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...
