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 ...

Two-Pion Exchange in proton-proton Scattering

The cross section and the spin-correlation observable, CNN, measured in the region from 0 to 12 GeV/c Plab at 90 o provide an excellent testing ground for our theories of hadronic interactions. These data have been the focus of a number of experimental [1] and theoretical studies [2]. There is an apparent simplification of the amplitude in the region from 4 GeV/c to 8 GeV/c. At 90 ◦ the spin-co...

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...

Effect of Pion-Pion Scattering Resonance on Nucleon Structure and Pion-Nucleon Scattering at Low Energies

The effect of pion-pion scattering resonance on the isovector part of nucleon structure is analysed by a method similar to that of Frazer and Fulco, but with one more subtraction for dispersion relations on helicity amplitudes of nucleon·aritinucleon production process in order to remedy the divergence regarding the left-hand cut. If the subtracted spectral representations are used for the form...

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 ...
