It is shown that /sup 12/B nuclei produced in the /sup 12 /C(/b n/ oarr ,/b p/)/sup 12/B reaction are polarized. The polarization of /sup 12/B is measured through its beta-decay asymmetry. The analyzing `efficiency' epsiv =/b P//sub N///b P //sub n/ (/sup 12/B polarization versus that of the incident neutron) for longitudinally polarized neutrons of average energy /b E/ macr /sub n/=18 MeV is: | epsiv |=0.11+/-0.02.
