Fundamental Experiments at Liquid Helium Temperatures (Low Temperature Studies of Anomalous Surface Shielding and Related Phenomena).

Abstract

It was found that an electron in an evacuated dewar, falling under the influence of gravity, experiences a net force of 10(-5) to 10(-7) V/m from 300 to about 4.5 degrees-K. At 4.5 degrees-K there is a transition to a net force of zero to within 6 x 10(-12) V/m. This effect has been traced to the creation of a 2-D surface plasma of free electrons on the walls of the copper free-fall tube at the transition temperature.
