The measurements are performed using a magneto-optical trap which is loaded from a laser-cooled, bright beam of slow He(23S) atoms. The data are compared with predictions from convergent close coupling and R matrix with pseudostate calculations, and we find good agreement between experiment and theory.4 pagesapplication/pdfen-AUKeywords: Close coupling; Laser-cooled; Low energy; Scattering cross sections; Atoms; Cooling; Electromagnetic wave scattering; Electron mobility; Electron traps; Laser applications; HeliumElectron collisions with laser cooled and trapped metastable helium atoms: total scattering cross sections200510.1103/PhysRevLett.94.1732012015-12-11
