It is well known that a light, pseudo-scalar particle called the Axion can solve
several fundamental physics problems. Proposed to explain the lack of a neutron
EDM, such a weakly interacting particle has the right characteristics to explain
formation of galaxies, by providing the needed mass in the form of Cold Dark
Matter. Additionally, there has been data collected on the decay of several
radioactive nuclei suggesting the need for weakly interacting particles
streaming from the sun and throughout the galaxy. This talk will review the
theory behind axion particles, examples of early experimental searches and some
new search techniques. The nuclei data reviewed here can provide complimentary
results to any existing axion searches as well as a novel type of search that
can be conducted.
