Number 6 (Story #2), October 25, 1990 by Phillip F. Schewe and Ben Stein THE SEARCH FOR THE ELECTRIC DIPOLE MOMENT of the electron has produced a new experimental limit. A group at the University of California at Berkeley, using a pair of counter-propagating beams of thallium atoms, has established a new upper limit of -2.7±8.3 x 10-27 e-cm, a factor of at least seven smaller than all previous measurements. The existence of a nonzero electron electric dipole moment would imply a violation of both parity invariance and time-reversal invariance. (Upcoming article in Physical Review Letters.
