Prediction of Deuteron Polarization fromd−αScattering

There is current interest in possible means of producing and analyzing deuteron polarization. Studies of d- alpha scattering on the 1.07-Mev resonance and the T(d,n)He/sup 4/ reaction show that d- alpha scattering can be a useful producer (and analyzer) of deuteron polarization at energies between resonances, where the weak energy dependence may be an advantage. The phase shifts of Galonsky and McEllistrem, deduced from differential cross sections with the help of dispersion theory, were used to calculate dispersion parameters in the interval between the resonances at 1.07 and 4.6 Mev.
