- Electron collisons with cyclobutane M. H. F. Bettega A. R. Lopes M. A. P. Lima L. G. Ferreira Física, Astronomía y Matemáticas Norm Cyclobutane Isomer effect conserving pseudopotentials We report integral, differential, and momentum transfer cross sections for elastic scattering of low-energyelectrons by cyclobutane (c-C4H8), which is an isomer of the C4H8 molecule and has a closed chain. Our calculationswere performed with the Schwinger multichannel method with pseudopotentials at the static-exchangelevel of approximation, for energies up to 50 eV. We compare the cross sections of cyclobutane with the crosssections of other three isomers of C4H8, namely, isobutene, cis-2-butene, and skew-1-butene. These isomershave open chain and were the subject of a previous study by our group [Lopes et al. J. Phys. B 37, 997 (2004)].We also show previous calculated integral and momentum transfer cross sections for isomers of C3H4, C3H6and C4H6, which have open and closed chains. For each isomeric group we discuss the isomer effect focusingon the closed chain isomer. The isomer effect is related to differences in the isomers cross sections due todifferences in their geometries. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46403618 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2B Vol.36
