Here we present measurements of dissociative and non-dissociative cross-sections for the electron impact CF4 molecule. The experiments are based on a Recoil Ion Momentum Spectrometer (RIMS), standard gas mixing setup CF4, reference gas. were carried out at several energies up to 1 keV, covering energy range previous experiments. We apply relative flow technique (RFT) convert measured by RIMS into absolute values. Using combination RFT, ion collection calibration errors minimized. results...
In this study, we present a complete set of electron scattering cross-sections from 1-Methyl-5-Nitroimidazole (1M5NI) molecules for impact energies ranging 0.1 to 1000 eV. This information is relevant evaluate the potential role 1M5NI as molecular radiosensitizers. The total (TCS) that previously measured with magnetically confined transmission apparatus were considered reference values analysis. Elastic calculated by means two different schemes: Schwinger multichannel (SMC) method lower...
This paper reports the structure and intermolecular potential energy curve (PEC) of heteroaromatic thiophene dimers obtained using a cold-target recoil-ion momentum spectroscopy reaction microscope. The three-dimensional momenta kinetic release (KER) ${\mathrm{C}}_{4}{\mathrm{H}}_{4}{\mathrm{S}}^{+}+{\mathrm{C}}_{4}{\mathrm{H}}_{4}{\mathrm{S}}^{+}$ ion pairs are by coincident measurement. two-body dissociation channel is initiated either rapid removal one outer-valence electron from each...
We report a combined experimental and theoretical study of the ionization dynamics tetrahydrofuran induced by 250 eV electron impact in which highest occupied molecular orbital is ionized leading to stable parent ion. Experimentally reaction microscope was used, covering nearly entire $4\ensuremath{\pi}$ solid angle for ejected slow electron. present triple-differential cross sections projectile scattering angles ${\ensuremath{\theta}}_{1}$ = $\ensuremath{-}{10}^{\ensuremath{\circ}}$ as...
Synopsis In order to study ultracold gases by photoionization within a Reaction Microscope (ReMi), we investigate new magneto-optical trap (MOT) configuration for cooling and trapping the atoms. Here present simulation results. comparison with conventional MOT, MOT has four laser beam axes. Two radial axes along x y directions two inclined ± 45 0 MOT/Feshbach coil axis (z axis).
Ionization of the $3p$ orbital argon (Ar) monomers, dimers (${\mathrm{Ar}}_{2}$), and small-size Ar clusters (${\mathrm{Ar}}_{n},\phantom{\rule{0.16em}{0ex}}\ensuremath{\langle}n\ensuremath{\rangle}\ensuremath{\approx}15$) is investigated for 90-eV electron impact. Experimentally, three-dimensional momentum vectors two outgoing electrons residual ion are measured in triple coincidence, as mass-over-charge ratio ion, using a reaction microscope that covers large part final-state phase space....
