We have formed polarized muonic {sup 3}He by stopping unpolarized negative muons in a gaseous {sup 3}He target which was polarized by spin exchange with laser optically pumped Rb vapor. We measured {ital P}{sub {mu}}{sup {ital N}}, the resulting muon polarization normalized to the nuclear polarization of the {sup 3}He. In addition to being a property that characterizes the muon cascade in the {mu}-{sup 3}He system, {ital P}{sub {mu}}{sup {ital N}} is of practical value for future experiments on nuclear muon capture. Our result, {ital P}{sub {mu}}{sup {ital N}}=0.072{plus minus}0.008, is a factor of 2 smaller than predicted by simple atomic cascade theory.
