Abstract

Cross sections for the (e, xn) reaction on 197Au have been measured for 1 ≦ x ≦ 12 at 37, 72, 124 and 147 MeV bombarding energies using activation methods. Data for x ≦ 2 are compared with cross sections estimated from published (γ, n) and (γ, 2n) data integrated over the virtual photon spectrum. Theoretical cross sections for x ≧ 4 were calculated by means of an intranuclear cascade model. Good agreement is found for x ≦ 7. The increasing discrepancy between experimental and theoretical cross sections for x ≧ 7 is discussed. No evidence is found for giant resonances in regions above the giant dipole resonance.
