dc.description.abstractEn | The polarization of ${34}$Al fragments, produced by single neutron pickup from a ${9}$Be target by a ${36}$S projectile at 77.5 MeV/nucleon, have been observed at GANIL via the detection of resonantly destroyed $\beta$-asymmetry. The reaction-induced polarization is deduced using a tentative spin/parity assignment for the $^{34}$Al ground state. A positive polarization was measured near the peak of the $^{34}$Al yield curve. A kinematical model based on the spectator-participant model for projectile fragmentation reactions has been extended in order to take into account the features of pickup reactions, i.e., the picked-up nucleon having an average momentum equal to the Fermi momentum and aligned along the incident beam direction. The trend-line in the observed spin-orientation is very well reproduced by this model. | |
