Title: Apparatus for time-resolved and energy-resolved measurement of internal conversion electron emission induced by nuclear resonant excitation with synchrotron radiation

Abstract

A high-energy and large-object-spot type cylindrical mirror analyzer (CMA) was constructed with the aid of electron trajectory simulations. By adopting a particular shape for the outer cylinder, an energy resolution of 7% was achieved without guide rings as used in conventional CMAs. Combined with an avalanche photodiode as an electron detector, the K-shell internal conversion electrons were successfully measured under irradiation of synchrotron radiation at 14.4 keV in an energy-resolved and time-resolved manner.

  • Nuclear resonant scattering of synchrotron radiation from [sup 119]Sn nuclei at 23.87 keV has been observed. The combination of a novel nested crystal monochromator and a [sup 119]SnO[sub 2]/Pd based grazing incidence antireflection film was used to investigate the Moessbauer parameters of a tin containing powder sample in a forward scattering experiment.

  • With U/sup 235/ as an example, it is stated that it is possible to observe excitation of isomeric nuclear levels via electron capture from the continuous spectrum on the electron shells freed by the action of laser radiation, and the possibility of transferring to the nucleus the energy of this capture, i.e., via the mechanism of inverse internal electron conversion. (AIP)
  • The pulsed nature or time structure'' of synchrotron radiation from electron storage rings is used to measure the kinetics of the decay of electronically excited states and is particularly useful because the wavelength of excitation can be chosen at will. However, changes in the length of the pulses of radiation from a storage ring resulting from the gradual decrease of current circulating in the ring during the course of a fill'' limit the duration of data collection, and hence photometric sensitivity. A fourth-harmonic cavity that was recently added to the vacuum ultraviolet (VUV) storage ring at the National Synchrotron Lightmore » Source slows the loss of current during a fill, and thus increases the total number of photons produced. When operated in a passive (unpowered) mode, however, the fourth-harmonic cavity increases both the average width of the photon pulses and the changes in width that occur during a fill, thus reducing the usefulness of the VUV ring in timing experiments. We demonstrate that operating the fourth-harmonic cavity in an active (powered) mode, while further increasing pulse duration, can stabilize pulse width, thereby restoring timing capabilities.« less
  • Cleaved GaAs surfaces decompose under weak pulsed-laser irradiation, leading to the formation of metallic Ga islands. The reduction of band bending nonuniformities in photoemission spectra acquired during the laser pulses, in concert with new core-level fitting techniques which treat broadened spectra, permits a detailed analysis. A decomposition rate consistent with a two-step photochemical excitation process is measured. The surface remains largely intact on an atomic scale, but is increasingly unable to support excited surface states as decomposition proceeds.
