Spin-dependent momentum distributions in deformed-nuclei
We study the properties of the spin-dependent one-body density in momentum space for odd-A polarized deformed nuclei within the mean field approximation. We derive analytic expressions connecting intrinsic and laboratory momentum distributions. The latter are related to observable transition densiti...

| Resumo: | We study the properties of the spin-dependent one-body density in momentum space for odd-A polarized deformed nuclei within the mean field approximation. We derive analytic expressions connecting intrinsic and laboratory momentum distributions. The latter are related to observable transition densities in p-space that can be proved in one nucleon knockout reactions From polarized targets. It is shown that most of the information contained in the intrinsic spin-dependent momentum distribution is lost when the nucleus is not polarized. Results are presented and discussed for two prolate nuclei, Ne-21 and Mg-25, and for one oblate nucleus, Ar-37. The effects of deformation are highlighted by comparison to the case of odd-A nuclei in the spherical model. |
