Theoretical and experimental study of electron impact ionization (e,2e) of the R-Carvone molecule for an intermediate incident electron energy*

We will present preliminary results from a combined theoretical and experimental study of electron impact single ionization of the R-Carvone molecule. The study was performed for a 250 eV incident electron energy, an ejected electron energy of 20 eV, and for three fixed scattered electron angles (5$^{\mathrm{o}}$, 10$^{\mathrm{o}}$, and 15$^{\mathrm{o}})$ in asymmetric coplanar geometry. Experimental data were measured for the three unresolved outermost orbitals - the highest, next highest, and next-next highest occupied molecular orbitals (HOMO, NHOMO, and HOMO-2). The generation of fully differential cross sections for this large molecule is extremely challenging for both experimental measurements and theoretical calculations. Theoretical M3DW (molecular 3-body distorted wave) results are summed over the three unresolved states to enable the comparison with the experimental data.
