โœฆ Synopsis

As a first step in the eventual measurement of the electron energy loss cross sections for atomic carbon, a 100 eV incident energy, 2" scattering angle electron energy loss spectrum of atomic carbon showing the 7.48 eV ( 1657 A) and 7.94 eV ( 1561 A) multiplets has been obtained. The carbon atoms were produced by 308 nm XeCl excimer laser vaporization ofa graphite rod at a I50 Hz repetition rate. The measurement of the relative intensities of the two carbon multiplets, 2sz2pz3P~2s22p3s F' and 2s22p2'P~2s2p3'Dc, allows their relative oscillator strengths to be calculated. The results are in excellent agreement with theoretical values and experimental lifetime measurements.
