[en] In this work we report calculated cross sections for elastic scattering of low-energy electrons by tetrahydropyran (C_5H_1_0O) molecule. We employed the Schwinger multichannel method (SMC) [5] implemented with pseudopotentials (SMCPP) in the static-exchange (SE) approximation for energies up to 30 eV. We compare our calculated cross sections with previous results obtained for cyclohexane and 1,4-dioxane molecules, since their geometrical structures are similar. We found that the differential cross sections obtained in the SE approximation present similar behavior for the three molecules except at lower angles, where the dipole moment present in tetrahydropyran increases abruptly the differential cross sections.
