Tensor polarization of deuterons in alpha-deuteron elastic scattering

Gerald G Ohlsen if one polarized particle is in the initial and one is in the final channel, we refer to a ' polarization transfer' experiment. We consider mainly particles with spin and with spin 1 ; to a minor extent higher spins are included. T h e state of the art with respect to the production of polarized beams and targets and with respect to polarization analysing devices is briefly reviewed. A considerable amount of space is devoted to the definitions of Cartesian polarization transfer and spin correlation coefficients which are suitable for the description of reactions involving spin + and spin 1 particles. These parameters are generalizations of the triple scattering and spin correlation parameters introduced by Wolfenstein for a description of nucleonnucleon scattering. Finally, the experiments of these types so far performed are reviewed. Reactions involving photons are excluded, and the nucleon-nucleon problem is only briefly mentioned.This review was completed in March 1972.7 This review is almost completely confined to reactions in which there are two initial and two final particles. Also, the word 'scattering' is frequently used in a general sense to include the possibility of a nuclear reaction.J 2 O l O (2.14) 1 ( $ ) ( S . 8, sz>= sus, sus, sus2 * ( szsx sas, sass SZSX sxs, sxszThese nine operator products could themselves be used for the basis ; however, we would like to retain the scalar (unit matrix) and vector operators already defined. Thus, we need to alter this tensor in several ways to arrive at the 'standard' Cartesian tensor. First, we write the tensor as a sum of a symmetric and antisymmetric part.
