A source of polarized electrons based on photoemission of GaAsP.
1990
Abstract The source described is based on photoemission of electrons from 100-GaAs0.62P0.38 activated to negative electron affinity. It is built to inject a beam of polarized electrons into the 350 MeV linear accelerator in Mainz. It is capable of delivering a mean current of 28 μA spin-polarized longitudinally to a degree of 0.44. The lifetime of the cathode under operational conditions is better than 200 h. The source was successfully run in a parity experiment, in which the analysing power of quasielastic scattering from beryllium for longitudinally polarized electrons was measured.
Untersuchung der beiden ersten angeregten Zustände des Li6-Kernes durch Elektronenstreuung
1969
Inelastic electron cross sections for Li6 were measured using the facilities at the 300 MeV linear accelerator of the Institut fur Kernphysik in Mainz. The form factor for theC 2 transition to the 2.184 MeV level is given in the region of momentum transfer 0.4 fm−1<q<1.9 fm−1. It was possible to determine the form factor for the 3.562 MeVM 1 transition up toq=1.2 fm−1.
