Effective solid angle correction factors for long-lived Auger states populated in low-Z ion collisions with gas targets

Abstract

SynopsisEffective solid angle correction factors for two high resolution electrostatic spectrometers - a hemispherical and a tandem parallel plate – are determined using SIMION Monte Carlo simulations. Results are compared to experimental correction factors directly determined from Auger spectra produced by 1s ionization in collisions of 6.6 MeV C2+ (1s22s2 1S, 1s22s2p 3P) mixed state ion beams with H2 targets. Excellent agreement between simulation and measurement is found.
