Spin-polarized Na-27 and Al-31 secondary beams have been produced at GANIL by the fragmentation of a 77.5 MeV/nucleon S-36(16+) primary beam onto a Be-9 target. The primary beam was deflected at an angle of -2(1)degrees with respect to the entrance of the LISE3 spectrometer, where the target was placed. For linear momenta higher than that of the S-36 projectiles, a deduced spin polarization P=-6.2(9)% and P=-1.5(4)% was obtained for Na-27 and Al-31 projectile fragments. These results demonstrate for the first time that fragments far from the projectile mass can be substantially polarized.
