AB  - Exotic spin dependent interactions can be meditated by ALPs(Axion Like Particle). Not only ALPs are possible candidates for dark matter, but also they might provide the most promising solution to the strong CP problem. Furthermore, recently, various models of new physics beyond the standard model have been studies in which new massive particles such as axion, familon, and majoron, etc. were theoretically introduced. Many of these exotic new interactions are spin dependent. For these interactions to be detected, the source or the probe particles have to be spin polarized. Spin polarized neutron beam, atom beam or noble gases are good probes to detect these new interactions. We proposed to use <sup>3</sup>He atom beams to search for three types of new interactions [1]. Using the atom beam method, sensitivities on three different types of spin dependent interactions could be improved by as much as 10<sup>2</sup> to 10<sup>8</sup> over the current experiments at the millimeter range. We Searched for New Spin- and Velocity-Dependent Interactions by spin relaxation of polarized <sup>3</sup>He Gas. Using the best available measured T<sub>2</sub> of polarized <sup>3</sup>He gas atoms as the polarized source and the Earth as an unpolarized source, we obtain constraints on two new interactions. We present a new experimental upper bound on possible vector–axial-vector (VVA) type interactions for ranges between 1 and 10<sup>8</sup> m[2].
