The laboratory is mainly devoted to study rarely occurring natural phenomena such as the interactions of neutrinos of cosmic origin or dark matter with atomic nuclei.
One of the earliest uses of the term interaction was in a discussion by Niels Bohr in 1913 of the interaction between the negative electron and the positive nucleus.
He was interested in studying the chemistry of the nucleus.
At least one possible channel of decay must include either a photon, a charged lepton or a meson, each of which would be energetic enough to destroy a nucleus if it strikes one.
In NDP, a thermal or cold neutron beam passes through a material and interacts with isotopes that emit monoenergetic charged particles upon neutron absorption; either a proton or an alpha, and a recoil nucleus.

In Nuclear magnetic resonance the introduction of the paramagnetic group increases the relaxation rate of nearby nuclei.
The first experiment to successfully detect cosmic neutrinos was Ray Davis's chlorine experiment, in which neutrinos were detected by observing the conversion of chlorine nuclei to radioactive argon in a large tank of perchloroethylene.
Nuclear fission, where a large atomic nucleus (such as that of uranium) is split into two (or sometimes more) smaller nuclei.
