The composite nature of baryons manifests itself in the existence of a rich spectrum of
excited states, in particular in the important mass region 1–2 GeV for the light-flavoured …

This review treats the advances in Light Baryon Spectroscopy of the last two decades, which
were mainly obtained by measuring meson-production reactions at photon facilities all over …

The photoproduction of 2 π 0 mesons off protons was studied with the Crystal Barrel/TAPS
experiment at the electron accelerator ELSA in Bonn. The energy of photons produced in a …

We review the last two decades of using photon beams to measure the production of
mesons, and in particular the information that can be obtained on the spectrum of light, non …

The production of η and η′ mesons in photon-and hadron-induced reactions on free and
quasi-free nucleons and on nuclei is reviewed. The extensive database on γ N→ η N, for …

The photoproduction of η mesons off nucleons bound in H 2 and H 3 e has been measured
in coincidence with recoil protons and recoil neutrons for incident photon energies from …

Photoproduction of π 0 π±-pairs from quasifree nucleons bound in the deuteron has been
investigated to study the helicity dependence of this reaction. Measurements with a liquid …

The tagged quasi-free np→ np π+ π− reaction has been studied experimentally with the
High Acceptance Di-Electron Spectrometer (HADES) at GSI at a deuteron incident beam …

Coherent photoproduction of π 0 π 0 and π 0 η on nuclei with A≤ 7 is systematically studied
in the energy region from the threshold to the laboratory photon energy E γ= 2 GeV. The …

This work measured dσ/dΩ d σ/d Ω for neutral kaon photoproduction reactions from
threshold up to a cm energy of 1855MeV, focussing specifically on the γp→K^0Σ^+ γ p→ K 0 …
