Abstract

We have polarized theJ = 0,I = 2 spins in solid D2 in 14.5 T to 13%. We condensed D2 in the form of small particles in a Pomeranchuk cell attached to a large dilution refrigerator. In this way we could cool the spins to 35 mK. The polarization was measured using cw NMR and a relaxation time at 35 mK of 360 sec was obtained in a hole burning experiment.
