Abstract

A Coulomb polarimeter primarily to determine the nuclear polarization of a polarized ²³Na beam is described. Coulomb excitation of ²³Na to its first excited state is used. The excited projectiles are identified by coincidences between inelastically scattered particles and deexcitation γ-rays. First results obtained with the polarimeter are in agreement with former experiments for the second rank tensor polarization of such a beam. The first rank tensor polarization of a polarized ²³Na beam could be measured as well.

Funding Information:
The source for polarized heavy ions at the MP tandem plus postaccelerator facility at the Max-Planck-Institut ffir Kemphysik in Heidelberg delivers polarized 23Na beams of all possible tensor ranks [1,2]. The nuclear and electronic polarization of the atomic beam in the source itself can be determined and monitored d charge exchange in the andafter strippingat the terminal of the MP tandem accelerator a fraction of the polarization is lost due to hyperfine interaction of the polarized 23Na nuclei with their electronic shell [1,2]. Thus, a continuous measure- ment of the beam polarization at the target is required . A general method to determine the polarization of heavy ion beams is the excitation of the projectile in the Coulomb field of a heavy target nucleus [4,51. As long as the nuclear potential is negligible analyzing powers for Coulomb excitation can be calculated exactly within the framework of coupled channel calculations .
