Production of spin-polarized 17N beam using inverse-kinematics low-energy transfer reactions

A new method to produce spin-polarized radioactive nuclear beams has been developed, which takes advantage of the low-energy transfer reaction in inverse kinematics. The method provides beam energies of a convenient range so that they may be implanted in a thin stopper, yet allowing the stopper to be spatially separated from the production target. The presence of polarizations of sizes at least \(\left|P\right|\sim 0.5 \%\) has been confirmed for a 17N beam obtained from 9Be(18O,17N) reaction at \(\theta_{\rm Lab} \sim -1.7\,^{\circ}\).
