Applications of the Schwinger multichannel method with pseudopotentials to electron scattering from polyatomic molecules I: elastic cross sections

Low to intermediate energy elastic electron scattering from dichloromethane (CH2Cl2)

“…Overall, we find a fairly good agreement between the experimental DCS and the MCOP data at angles up to 90°. At 5eV, the SMC data of Natalense et al [21,22] also agree well with our data. At 10eV, our experimental DCS show very good agreement with both the present MCOP results and the SMCPP data of Krupa et al [24].…”

“…At θ30°, only four experimental data were reported by Krupa et al Despite that, their DCS and ours from the CSUF show very good agreement. In figure 2, the experimental DCS obtained by both the CSUF and the UFSCar groups at E=20 and 30eV are compared with the MCOP results, the calculated and measured data of Krupa et al [24], and the SMC results of Natalense et al [21,22]. It is seen that there is a very good agreement between the CSUF and UFSCar data.…”

“…A comparison of the experimental DCS with our theoretical results, calculated at MCOP and IAM levels of approximation, and with the calculated and measured data of Krupa et al [24] is shown in figures 1-3. In the 5-30eV E range, the theoretical results of Natalense et al [21,22] using the SMC approach without the inclusion of polarization effects are also shown. In figure 1, our measured data of CSUF group at 1, 3, 5, and 10eV are compared with the present calculated results using the MCOP approach.…”

“…In section 3, the theory and details of the UFSCar calculations are presented. In section 4, we present the experimental and theoretical results with comparisons between them and with other results available in the literature [13,21,22,24]. In section 5, we summarize our work with some conclusions.…”

“…On the theoretical side, DCS and momentum-transfer cross sections (MTCS) were reported by Natalense et al [21,22] in the 5-30eV E range using the Schwinger multichannel method (SMC) with and without pseudo-potentials (SMCPP), the latter includes polarization effects. Also, TCS, integral elastic cross sections (ICS) and total absorption cross sections (TACS) in the 20-5000eV range were calculated by Naghma et al [23] using the spherical complex optical potential (SCOP) approach.…”
