“…The present results show a strong peak of about 44 Å 2 positioned at about 3.8 eV using 6-31G* and 46.0 Å 2 positioned at 3.4 eV using DZP. This feature is also seen in experimental results of Brüche 19 15 (50.8 Å 2 at 2.6 eV). Present theoretical data yields lowest peak compared to all theoretical data 14,15,17,18 and data closer to experimental investigations.…”

Comprehensive study on electron impact for acetylene molecule is performed in terms of eigenphase diagram, electronic excitation cross sections as well as total cross section calculations from 1 eV to 5000 eV in this article. Computation of cross section over such a wide range of energy is reported for the first time. We have employed two distinct formalisms to derive cross sections in these impact energies. From 1 eV to ionization threshold of the target we have used the ab initio R-matrix method and then spherical complex optical potential method beyond that. At the crossing point of energy, both theories matched quite well and hence prove that they are consistent with each other. The results presented here expectedly give excellent agreement with other experimental values and theories available. The techniques employed here are well established and can be used to predict cross sections for other targets where data are scarce or not available. Also, this methodology may be integrated to online database such as Virtual Atomic and Molecular Data Centre to provide cross section data required by any user.

“…From Table I we can see that there are substantial low energy scattering studies on this target both theoretically 14,15,17,18 as well as experimentally. 16,19 The case of intermediate to high energy regime is also not different. There are significant contributions from the theoretical [21][22][23] and the experimental groups.…”

“…However, Brüche 39 used a single-segment scattering cell with a worse angular resolution. Brüche's paper 32 concentrates on similarities between cross sections in N 2 and C 2 H 2 . He reported three measurements, with two different gas samples and using ''old'' and ''new'' apparatus.…”

Cross section data are compiled from the literature for electron collisions with the acetylene (HCCH) molecule. Cross sections are collected and reviewed for total scattering, elastic scattering, momentum transfer, excitations of rotational and vibrational states, dissociation, ionization, and dissociative attachment. The data derived from swarm experiments are also considered. For each of these processes, the recommended values of the cross sections are presented. The literature has been surveyed through early

“…Karwasz and coworkers [9] have reviewed the body of work up to 2001. Total scattering cross sections were measured at low energies by Brüche [10] and by Sueoka and Mori [11], and, more recently, at intermediate and high energies by Xing and coworkers [12], Ariyasinghe and Powers [13], and Iga and coworkers [14]. Total cross sections above 10 eV have been calculated using a number of simplified models [15][16][17][18].…”

We report measurements and first-principles calculations of the differential cross sections for elastic scattering of low-energy electrons by acetylene, C 2 H 2 , at collision energies from 1 to 100 eV, with an emphasis on energies near and below that of the π * shape resonance. The measurements cover angles from 5• to 130• . We compare our results to previous experimental and theoretical values.
