Polarization of 23 Ne, 24m,25 Al and 28 P produced through single nucleon pickup and charge-exchange reactions at 100 A MeV

We measured the polarization of the -emitting 23 Ne ( I π = 5/2 + , T 1/2 = 37.24 s) and 25 Al( I π = 5/2 + , T 1/2 = 7.18 s) produced through the one nucleon pickup reactions and 24m Al( I π = 1 + , T 1/2 = 131 ms, E ex = 426 keV) and 28 P( 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.
