Elastic scattering of electrons by benzene

Cross sections for elastic electron collisions on two hydrocarbon compounds:n-butane and benzene in the intermediate-energy range

“…At 300 eV and above, there is a general good agreement (about 25% of discrepancy). At 300 eV and 500 eV, the normalized DCS of Mahant Shetty et al [25] agree very well with our experimental data in the overlapped angular range. At 1000 eV, the absolute DCS of Boechat-Roberty et al are reported only at scattering angles up to 13 • , therefore do not overlap with our data.…”

“…In figures 6-8, we compare the experimental DCS for elastic electron scattering by benzene in the (50-1000) eV incident energy range with the experimental results of Boechat-Roberty et al [24] at 1000 eV and with the relative DCS of Mahant Shetty et al [25] at 300 eV and 500 eV, normalized to our absolute data at 40 • . The present calculated data using the IAM at the SEP level of approximation in the energy range covered herein and the calculated data of Ma et al [27] also using the IAM but at SEPA level at 100 eV and above are also shown.…”

“…Very recently, DCS at very limited scattering angles were reported by Boechat-Roberty et al [24] at the incident energy of 1000 eV. Some relative DCS for elastic scattering by benzene at (300-900) eV energy range and 30 • -120 • angular range were reported by Mahant Shetty et al [25].…”

“…In equation ( 2), s = 2k sin θ 2 is the magnitude of the transferred momentum during the collision and k is the magnitude of the linear momentum of the incident electron. The symbols used are the same as in figure 6, except: open circles, relative DCS of Mahant Shetty et al [25], normalized to our data at 40 • .…”

“…Figure 7. Same as in figure 6, but for (a) 300 eV and (b) 400 eV.The symbols used are the same as in figure6, except: open circles, relative DCS of Mahant Shetty et al[25], normalized to our data at 40 • .…”
