Experiment E155 at the Stanford Linear Accelerator Center (SLAC) measured t
he spin-dependent structure of the proton and neutron, using for the first
time (LiD)-Li-6 as the polarized deuteron target material in a high-energy
electron beam. This compound provides a significantly higher dilution facto
r than any other solid deuteron target material currently used in high-ener
gy physics experiments. Results of the polarization behavior of the (LiD)-L
i-6 target material before and after exposure to the 50 GeV/c electron beam
used in E155 are presented. (C) 1999 Elsevier Science B.V. All rights rese
