Differential cross sections for the $\ensuremath{\gamma}p\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}n$ reaction have been measured at photon energies 1 to 2 MeV above threshold using tagged-photon beams. The electric dipole amplitude ${E}_{0+}$ de

In order to initiate the experiments using linearly polarized tagged photons at intermediate energies, it is imperative to know and to monitor the degree of polarization. The relationship is re-examined between the linear polarization of photons and

A segmented neutron detector has been constructed and used for recoil neutron (6–13 MeV) measurements of the reaction γp→nπ+ very close to threshold. BC-505 liquid scintillator was used to allow pulse shape discrimination between neutrons and p

We have observed x-ray emission from transition radiators placed inside an electron storage ring. The radiators were thin (0.18–9 μm) and the electrons were of sufficient energy (118–252 MeV) so that the electrons passed through the radiators ma
