Abstract

In this work, we report an experimental cross-section determination of elastic electron collisions with tetrahydrofuran in the intermediate-energy range. More specifically, absolute differential cross sections are measured and reported in the (50--1000) eV range. The measurements were performed using a crossed electron beam--molecular beam geometry. The angular distributions of the scattered electrons were converted to absolute cross sections using the relative flow technique. A procedure based on the method of initial rate is applied to determine the flow rate of vaporized liquid samples. Moreover, integral and momentum transfer cross sections are derived from the measured differential cross sections. Comparison is made between our measured data with the existing experimental results and with our theoretical results calculated using the independent atom model at the static-exchange-polarization plus absorption level of approximation.
