Helicity amplitudes A(1/2) and A(3/2) for the D-13(1520) resonance obtained from the (gamma)over-right-arrow(p)over-right-arrow -> p pi(0) reaction
Author
Summary, in English
The helicity dependence of the (γ) over right arrow(p) over right arrow -->ppi(0) reaction has been measured for the first time in the photon-energy range from 550 to 790 MeV. The experiment, performed at the Mainz microtron MAMI, used a 4pi -detector system, a circularly polarized, tagged photon beam, and a longitudinally polarized frozen-spin target. These data are predominantly sensitive to the D-13(1520) resonance and are used to determine its helicity amplitudes.
