摘要：

A new search for a permanent electric dipole moment of Hg-199 has yielded the null result d(Hg-199)= -(2.7 +/- 5.8) x 10(-28) e cm where the statistical and systematic uncertainty have been combined. This gives an upper limit of d(Hg-199) < 1.3 x 10(-27) e cm (95% confidence). The measurement sets the most stringent limits to date on several possible sources of time-reversal symmetry violation. We look for a relative shift in Larmor-precession frequency between two optically pumped Hg-199 atomic oscillators in the presence of applied electric fields. We have attained a statistical uncertainty on the relative shift in frequency between the oscillators of 2 x 10(-9) Hz.
