Abstract
We study the properties of the spin-dependent one-body density in mome ntum space for odd-A polarized deformed nuclei within the mean field a pproximation. We derive analytic expressions connecting intrinsic and laboratory momentum distributions. The latter are related to observabl e transition densities in p-space that can be proved in one nucleon kn ockout reactions From polarized targets. It is shown that most of the information contained in the intrinsic spin-dependent momentum distrib ution 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 ob late nucleus, Ar-37. The effects of deformation are highlighted by com parison to the case of odd-A nuclei in the spherical model. (C) 1995 A cademic Press, Inc.
