The result of a search for the electric dipole moment of the neutron is presented. A short review of past experimental work and theoretical predictions introduces a discussion of the experimental method used in, and the results obtained by, the present work. The weighted mean of three separate ...
The atomic electric dipole moment caused by a moment on the electron is calculated for the alkalis in their ground states. The ratio of the atomic to electronic moments is found to range from 4 × 10 3 for lithium to 10 3 for francium. PGH Sandars - 《Physics Letters》 被引量: 113发...
In particular, we analyze the zero modes analytically in various limits, both on ${\mathbf{R}}^{4}$ and on the four-torus, in order to compare with recent lattice QCD results, and study the implications for the electric dipole moment. 展开 ...
Theoretical studies are presented how the electric dipole moment (EDM) of the electron in H-like ions in electrostatic storage rings can sensitively be determined. With the proposed experiments a new constraint of about $10^{-29}$ e cm for the electron EDM can be established what is by an...
Appendix 1.4.A1 Dipole Moment A Dipole Consists of Two Equal Charges Separated by a Distance, d, and Is Described by its Electric Dipole Moment This appendix defines the dipole moment and derives an expression for its magnitude as a function of distance and angle from the center of the dipol...
7. An electric dipole with the dipole moment p is rotating in the r-z-plane in clockwise direction about an axis passing perpendicularly to the plane of rotation through the negative charge. The external electric field is generated by an infinitel...
We experimentally determine the conjecture that hydrogen-like atoms such as Rb and Cs may have large permanent electric dipole moments (EDMs). The saturated Rb vapour fills a cylindrical capacitor in the experiment. The influence of the vapour dielectric medium on capacitance is measured with a dig...
of the forces exerted by the two charges, as shown for two different positions. Because the force declines as 1/r2, the direction of the force changes with distance and angle,θ, made between the line joining the center of the dipole and the test charge, and the electric dipole moment....
