We measured the polarization of the β-emitting 23Ne (I π = 5/2+, T 1/2 = 37.24 s) and 25Al(I π = 5/2+, T 1/2 = 7.18 s) produced through the one nucleon pickup reactions and 24mAl(I π = 1+, T 1/2 = 131 ms, E ex = 426 keV) and 28P(I π = 3+, T 1/2 = 270 ms) produced through charge-exchange reactions in the intermediate energy heavy ion collisions. We compared them with those from the projectile fragmentation process. The larger polarization seems to persistently be positive throughout the momentum distribution, and sharper momentum distributions suggest that nuclear friction mechanism is responsible for the polarization phenomena.
