A theoretical and experimental investigation of two-center interference effects in electron impact ionization of diatomic molecules (H$_{\mathrm{2}}$ and N$_{\mathrm{2}})$.

In this work, we examine possible two-center interference effects by comparing triple differential cross sections (TDCSs) for electron impact ionization of an atom with the corresponding diatomic molecule for H2 and N$_{\mathrm{2}}$. The ratio of the TDCS for a diatomic molecule to the equivalent atomic TDCS (called the I-factor) is a sensitive test for interference effects. We will present the I-factor, for 350 eV electron impact ionization of H$_{\mathrm{2}}$ and N$_{\mathrm{2}}$, by comparing theoretical 3-body distorted wave approximation (3DW) results with experimental data measured at the e-COL laboratory.
