    "abstract": "We report the first study of the depolarization behavior of spin polarized\n3He in a mixture of 3He-4He at a temperature below the 4He Lambda point in a\ndeuterated TetraPhenyl Butadiene-doped deuterated PolyStyrene (dTPB-dPS) coated\nacrylic cell. In our experiment the measured 3He relaxation time is due to the\nconvolution of the 3He longitudinal relaxation time, T1, and the diffusion time\nconstant of 3He in superfluid 4He since depolarization takes place on the\nwalls. We have obtained a 3He relaxation time ~3000 seconds at a temperature\naround 1.9K. We have shown that it\u0027s possible to achieve values of wall\ndepolarization probability on the order of (1-2)x10^-7 for polarized 3He in the\nsuperfluid 4He from a dTPB-dPS coated acrylic surface.",
