As they go, the waves slightly displace atoms in the semiconductor, shifting positive atomic nuclei off center from their surrounding electrons and subtly altering the electric charge of the atoms.

In effect the negatively charged electrons and positively charged atomic nuclei respond to one another in a way that causes each to try to accommodate the «shape» of the other.

The ratio of charge to heat tells researchers whether the particle struck the nucleus, and therefore might be a WIMP, or if it is just a rogue electron or some other familiar particle that is simply stirring up the atomic neighborhood.

The sudden recoil of the atom's nucleus would trigger a shower of electrically charged particles and atoms as well as light and heat, which can be picked up by a sensor.

The ALICE experiment at the Large Hadron Collider (LHC) at CERN (1) has made a precise measurement of the difference between ratios of the mass and electric charge of light nuclei and antinuclei.

The measurement by ALICE comparing the mass - to - charge ratios in deuterons / antideuterons and in helium - 3 / antihelium - 3 confirms the fundamental symmetry known as CPT in these light nuclei.
