Tensor analyzing powers for 2H(d,p)3H and 2H(d,n)3He at deuteron energies of 25, 40, 60, and 80 keV.

Abstract

Angular distributions of the tensor analyzing powers [ital A][sub [ital z][ital z]] and [ital A][sub [ital x][ital x]][minus][ital A][sub [ital y][ital y]] for the reactions [sup 2]H([ital d],[ital p])[sup 3]H and [sup 2]H([ital d],[ital n])[sup 3]He are presented at deuteron energies of 25, 40, 60, and 80 keV. The analyzing powers for the two reaction channels are quite similar at these energies. The data have been included in an [ital R]-matrix analysis of the four nucleon system. According to this analysis, transitions from entrance-channel quintet-[ital S] states are important in these reactions, so that the use of polarized fuels would not result in a neutron-lean fusion reactor.
