First measurement of the helicity asymmetry for in the resonance region
M. Gottschall, A. V. Anisovich, B. Bantes +64
The first measurement of the helicity dependence of the photoproduction cross section of single neutral pions off protons is reported for photon energies from 600 to 2300\,MeV, cov…
Sign ambiguity in the K Sigma channel
A. V. Anisovich, E. Klempt, V. A. Nikonov +2
Ambiguities of the signs of coupling constants are studied in a multichannel partial wave analysis of a large body of pion and photo-induced reactions. It is shown that t…
Study of ambiguities in scattering amplitudes
A. V. Anisovich, R. Beck, E. Klempt +4
Amplitudes for the reaction are reconstructed from data on the differential cross section , the recoil polarization , and on the spin rotation parameter $β…
Helicity amplitudes for photoexcitation of nucleon resonances off neutrons
A. V. Anisovich, V. Burkert, E. Klempt +3
The helicity amplitudes and for the photoexcitation of nucleon resonances off neutrons are determined in a multi-channel partial-wave analysis.
