Excitation energy and strength of the pygmy dipole resonance in stable tin isotopes
B. Özel,Joachim Enders,H. Lenske,P. von Neumann-Cosel,I. Poltoratska,V. Yu. Ponomarev,Achim Richter,Deniz Savran,N. Tsoneva +8 more
TL;DR: In this paper, an experimental systematics of the pygmy dipole resonance (PDR) in stable even-mass tin isotopes is established, and the PDR centroid excitation energies and summed strengths are in reasonable agreement with quasiparticle-phonon model calculations based on a nonrelativistic description of the mean field.

TL;DR: Using a Compton polarimeter, the linear polarization of channeling radiation of 63 MeV electrons in silicon has been measured at the superconducting electron linear accelerator S-DALINAC.

Project review of the near-infrared free electron laser at the S-DALINAC☆
J. Auerhammer,Harald Genz,Hans-Dieter Gräf,H. Liu,Achim Richter,F. Thomas,J. Töpper,H. Weise +7 more
TL;DR: The Darmstadt superconducting electron accelerator S-DALINAC as discussed by the authors became fully operative at the end of 1990 and the first measurements of the spontaneous spectrum are scheduled for fall 1991.

Doorway-state analysis of the fragmentation of the magnetic-dipole strength in SU58 NI observed in high-resolution inelastic electron scattering
TL;DR: In this article, the fine structure of the magnetic-dipole strength in 58 Ni observed in high-resolution inelastic electron scattering at the DALINAC has been analyzed under the assumption that the measured distribution of the strong fragmented M1 strength results from a coupling of two doorway states to a large number of more complicated states.
