We measured the polarization of the {beta}-emitting 23Ne (I{pi} = 5/2+, T1/2 = 37.24 s) and 25Al(I{pi} = 5/2+, T1/2 = 7.18 s), produced through the one nucleon pickup reactions in the intermediate energy heavy ion collisions, and was compared with those from the projectile fragmentation process. The larger polarization which seems to persistently be positive throughout the momentum distribution, and sharper momentum distributions suggest nuclear friction mechanism to be responsible for the polarization phenomena. Using such a large polarization, magnetic moment of 23Ne and the quadrupole moment of 25Al were measured. The obtained values are |{mu}(23Ne)| = 1.0817(9) {mu}N and |Q(25Al)| = (240 {+-} 20) mb.
