摘要：

Absolute differential cross sections have been measured for elastic electron scattering from tetrahydrofuran in the electron impact energy from 6 to 20 eV and in a wide scattering angle range from 20 degrees to 180 degrees. In the measurements the magnetic-angle-changing technique has been employed to detect the backward scattering of electrons. The integral and momentum transfer cross sections for elastic scattering have been also determined through integration of the measured differential cross sections. A detailed comparison of the obtained differential cross sections has been made with the results of very recent theoretical calculations. In the measurements attention has been paid to observe negative-ion resonances predicted in these theoretical calculations.
