    Abstract

    The toroidal energy- and angle-resolving electron spectrometer (TEARES) is a state-of-the-art instrument, which enables both the energy and angle of ejection of an electron to be measured simultaneously. First synchrotron results from TEARES are presented in this progress report. Relative cross-sections and asymmetry parameters for the Argon 3s3p64p P1°1 'window' resonance region have been measured; the results are in good agreement with the previously published data of Codling et al. In addition, significant modifications have been made to the spectrometer, which have greatly enhanced its performance. The reasons for these changes and their resulting effects on the data are presented. © 2005 Elsevier B.V. All rights reserved.
