Abstract
Studies of weak localization by scattering from vapor atoms for electrons o n a liquid He-4 surface near 2 K are presented. The dephasing time due to t he motion of helium atoms perpendicular to the plane of electrons is studie d by increasing the DC electric field forcing the electrons against the sur face of the liquid. This contribution varies approximately linearly with th e spatial extension of the electron wave function. (C) 2000 Elsevier Scienc e B.V. All rights reserved.
