Description
Proton polarization of approximately 65% has been achieved with the University of Massachusetts ''spin refrigerator'' in a nonuniform 1.07-T field at 1.25 K. The free protons in (Yb, Y)(C2H5SO4)3 x 9H2O are polarized through sample rotation at 100--200 rps. Results represent the first confirmation of high polarization predicted by a single-Yb-ion interaction model since the original proposals of Jeffries and Abragam. The polarized proton target, with length equivalent to 9 cm of liquid hydrogen, will be utilized in studies of strange particles
