Die elektronenstreu-apparatur am mainzer 300 MeV-elektronen-linearbeschleuniger
Abstract In this paper, we attempt to give a general survey and a comprehensive description of the most significant features of the facilities for electron scattering experiments at the Mainz 300 MeV Linear Accelerator, along with a list of literature, where more detailed information on certain subjects can be found. The accelerator provides energies between 80 and 300 MeV. Scattering angles are available up to 160° resulting in a momentum transfer region up to 3.0 fm −1 . The overall experimental resolution is 0.1%. Cross sections down to 10 −34 cm 2 /sr can be measured. The main features of the apparatus are: an achromatic magnet system with 90° deflection, a double focusing spectrometer,…
Electron Scattering Experiments at the Mainz 300 MeV Linear Accelerator
The Mainz electron scattering facility provides energies between 80 and 300 MeV and scattering angles up to 158° which corres-pond to a useful momentum transfer region 0.4 ≤ q ≤ 3.0 fm−1. The accelerator and analyzing system produce approximately 1 μA average current with the overall resolution in the final spectra of usually 0.15% to 0.30%.
Zum ?-Spektrum von Po214 (RaC?)
Theγ-ray spectrum arising from Bi214→Po214 β-decay was investigated by means of a three-crystal-pair-spectrometer. In addition to many already known energies and intensities several new lines have been found, partly improved values for relative intensities are given. These results have been achieved by programming a computer to reproduce the obtained data in a trial and error procedure.
