EXPERIMENTAL STUDY OF THE GAS FLOWS THROUGH CHANNELS WITH CIRCULAR CROSS SECTIONS

The velocity slip and accommodation coefficients are deduced by using the experimental data of the mass flow rate and the Navier-Stokes model with the first and second order

Electron collisions with CO: Elastic and vibrational excitation cross sections

The present v = 1 cross sections, shown in Fig. 10, agree well with those of Gibson et al. below the resonance region but are slightly higher in the resonance region, as already

Absolute cross sections for dissociative electron attachment to acetylene and diacetylene

Because of its high energy this shape resonance is expected to have a large au- todetachment width, however, and the large magnitude of the dissociative electron attachment

Cross sections for vibrational excitation of H2(X 1Σ +g, ν" = 0) via electronically excited singlet states populated by low energy electron impact

Cross sections for vibrational excitation of H2(X 1Σ +g, ν” = 0) via electronically excited singlet states populated by low energy electron impact... The cross sections present a

Electron scattering in Pt(PF₃)₄: Elastic scattering, vibrational, and electronic excitation

(the cross section rises slightly near 0 ◦ at 10 eV for the energy-loss range A in Fig. 18, but this is presumably because 10 eV is already significantly higher above threshold than

Absolute angle-differential elastic cross sections for electron collisions with diacetylene

The 2 u resonance is too sharp in the calculated data, as expected for a fixed-nuclei calculation, but it is also too low in energy (about 0.47 eV instead of 1 eV), probably

Absolute angle-differential vibrational excitation cross sections for electron collisions with diacetylene

The distortion may be minor, for example, the C≡C bond lengthens because the π ∗ orbital into which the extra electron is accommodated is antibonding along the C≡C bond, or

Absolute cross sections for dissociative electron attachment to HCN and DCN

Absolute partial cross sections for the formation of CN − in dissociative electron attachment to HCN and DCN have been measured using a time-of-flight ion spectrometer combined with
