| heal.abstract | First high resolution measurements using a new electron spectrograph at 0 degrees to the beam direction are reported. The new apparatus consists of a hemispherical analyser with a mean radius of 101.6 mm, a 4-element focusing lens and 40 mm diameter 2-D position sensitive detector (PSD). Electrons are decelerated and focused in the lens prior to analysis to improve the energy resolution. As a test of the apparatus in deceleration mode, we measured the differential cross section of the F(7+)(2p(2))(1)D state produced by Resonance Transfer Excitation (RTE) in collisions of 21.78 MeV F(8+)+ H(2). An effective energy resolution of 0.25% was obtained using a deceleration factor of 4. Good agreement with known cross section Values was found. Presently, our spectrograph with a maximum count rate of about 4 kHz (limited by dead-time considerations) is more than 15 times faster than the conventional tandem zero-degree spectrometer at Kansas State University, while using a factor of 20 lower intensity beams.
