Neutron Electric Dipole Moment
The neutron electric dipole moment (nEDM) is a measure for the distribution of positive and negative charge inside the neutron. A finite electric dipole moment can only exist if the centers of the negative and positive charge distribution inside the particle do not coincide. So far, no neutron EDM has been found. The current best upper limit amounts to |dn| < 2.9×10−26e·cm.

Famous quotes containing the words electric and/or moment:
“The sight of a planet through a telescope is worth all the course on astronomy; the shock of the electric spark in the elbow, outvalues all the theories; the taste of the nitrous oxide, the firing of an artificial volcano, are better than volumes of chemistry.”
—Ralph Waldo Emerson (1803–1882)
“Inside the brain
Two memories that long had lain
Now quivered toward each other, lipped
Together, and together slipped;
And for a moment all was plain
That men have thought about in vain.”
—Robert Frost (1874–1963)
