Sign dependence of spin polarization for secondary fragments produced following intermediate-energy projectile fragmentation
The dependence of the spin polarization on the incident angle of the primary beam has been measured for 12B fragments produced in the fragmentation of an 18O beam on a Nb target at 80 MeV/nucleon. A change in sign of the spin polarization was observed with a change in sign of the incident angle of t...

| Summary: | The dependence of the spin polarization on the incident angle of the primary beam has been measured for 12B fragments produced in the fragmentation of an 18O beam on a Nb target at 80 MeV/nucleon. A change in sign of the spin polarization was observed with a change in sign of the incident angle of the projectile. This result is in agreement with the kinematical model presented recently to qualitatively describe the mechanism for the production of spin-polarized fragments following intermediate-energy heavy-ion reactions. The resonance curve for 12B has also been measured using a technique of multiple adiabatic fast passage with continuous implantation. This technique is briefly compared to the single-pass adiabatic fast passage method employed with beam-on/beam-off data acquisition. |
