Experimental measurements of low-energy elastic scattering of electrons from ions

Abstract

First experimental results are presented from a new electrostatic spectrometer designed to study electron scattering from positive ions. Measurements of elastic scattering from have been carried out over the centre-of-mass energy interval 12 - 24 eV for fixed scattering angles of , and . Results are compared with the Rutherford formula and a phaseshift calculation based on a semiempirical potential.
