Exclusive ?-particle and proton production measurements of the system Li6+Si28 are performed at near-barrier energies. Each reaction channel is tagged via a particle-? coincidence requirement. Ratios of direct to compound contributions are estimated via particle angular distribution measurements. Strong reaction channels for n and p transfer are identified and quantified and found to be described well on a qualitative basis with distorted-wave Born approximation calculations. © 2007 The American Physical Society.

The nuclear magnetic moment of the ground state of 57 Cu(I? = 3/2-, T1/2 = 196.3 ms) has been measured to be ?(57Cu) = (2.00 ± 0.05) ?N using the ?-NMR technique. Together with the known magnetic moment of the mirror partner 57Ni, the spin expectation value was extracted as ?? ?z? = -0.78 ± 0.13. Discrepancy between present results and shell model calculations in the full fp shell implies significant shell breaking at 56Ni with the neutron number N = 28. © EDP Sciences/Societe?

Total reaction cross section measurements for the 6,7Li + 28Si systems have been performed at near-barrier energies. The results indicate that, with respect to the potential anomaly at barrier, 6Li and 7Li on light targets exhibit similar energy dependence on the imaginary potential. Comparisons are made with 6,7Li cross sections on light and heavy targets, extracted via previous elastic scattering measurements and also with CDCC calculations. Energy dependent parametrisations are also obtained for total reaction cross sections of 6,7Li on Si, as well as on any target, at near barrier energies. © 2006 Elsevier B.V. All rights reserved.

Intermediate-energy heavy-ion collisions can produce a spin polarization of the projectile-like species. Spin polarization has been observed for both nucleon removal and nucleon pickup processes. Qualitative agreement with measured spin polarization as a function of the momentum of the projectile-like fragment is found in a kinematical model that considers conservation of linear and angular momentum and assumes peripheral interactions between the fast projectile and target. Improvements to the kinematical model are discussed that aim to achieve quantitative agreement with spin polarization data from both the nucleon removal and pickup processes. © 2007 American Institute of Physics.

Qualitative agreement with measured spin polarization as a function of the momentum of the projectile-like fragment is found in a kinematic model that considers conservation of linear and angular momentum and assumes peripheral interactions between the fast projectile and target. Better quantitative agreement was reached by including more realistic angular distributions and deorientation caused by ?-ray emission and by correcting for the out-of-plane acceptance. The newly introduced corrections were found to apply to both nucleon removal and nucleon pickup processes. © 2007 The American Physical Society.
