A Study of Influence of Synchrotron Radiation Quantum Fluctuations on the Synchrotron Oscillations of a Single Electron Using Undulator Radiation
A single electron circulating in a storage ring is a very peculiar object.
Synchrotron radiation quantum fluctuation causes stohastic process in the
synchrotron oscillation of an electron. The radiation from a undulator permits
one to obtain discret moments of longitudional electron motion. Experiments
with a single electron on on the VEPP-3 optical klystrons are described.Comment: 4 pages, LaTeX, 2 fig. incl. and 6 fig. appended as uudecoded_arj_pcx

Low-Energy Photodisintegration of the Deuteron and Big-Bang Nucleosynthesis
The photon analyzing power for the photodisintegration of the deuteron was
measured for seven gamma-ray energies between 2.39 and 4.05 MeV using the
linearly polarized gamma-ray beam of the High-Intensity Gamma-ray Source at the
Duke Free-Electron Laser Laboratory. The data provide a stringent test of
theoretical calculations for the inverse reaction, the neutron-proton radiative
capture reaction at energies important for Big-Bang Nucleosynthesis. Our data
are in excellent agreement with potential model and effective field theory
calculations. Therefore, the uncertainty in the baryon density obtained from
Big-Bang Nucleosynthesis can be reduced at least by 20%.Comment: 5 pages, 5 figure
