Abstract
We predict a possibility of triplet Cooper pairing in a Fermi-gas of neutral particles in a confined geometry of magnetic traps at ultra-low temperatures. We evaluate a superfluid transition temperature and analyze the difference between pairing in free space and in confined geometry. We also consider in details a case of fermionic 6Li.
