Probing Young-type interference effect on angular distributions of e-DDCS using fast electrons as projectile

We have studied Young-type interference in the energy and angular distributions of double differential cross sections (DDCS) of electrons emitted in single-ionization of H2, induced by 8 keV electron impact. The first-order interference is derived from the energy distribution of DDCS and the resulti...

Summary:We have studied Young-type interference in the energy and angular distributions of double differential cross sections (DDCS) of electrons emitted in single-ionization of H2, induced by 8 keV electron impact. The first-order interference is derived from the energy distribution of DDCS and the resulting ratio-spectra (H2-to-2H) exhibit oscillating behaviour. The signature of first-order interference is also demonstrated in the DDCS-spectra as a function of emission angle. We have shown that the constructive interference prevails in soft- and binary-collision regions. The single differential cross sections obtained by integrating the DDCSs over energy and solid angle also preserve the information on interference.
