Relaxation of Spin Polarized ${}^3$He in Mixtures of ${}^3$He and ${}^4$He at $\sim$330 mK

Q. Ye, H. Gao, W. Zheng +6

We report the measurements of depolarization probabilities of polarized ${}^3$He in a rectangular acrylic cell with a deuterated tetraphenyl butadiene-doped deuterated polystyrene co…
