Abstract
The spin alignment of recoil deuterons in high-energy elastic scattering at 180° is calculated in two models. One is the simple nucleon-transfer or pickup mechanism. The other is the extended pickup mechanism of Kerman and Kisslinger that includes, in addition to nucleon exchange, the exchange of resonance which is taken to be present in the deuteron with a small (1-2%) probability. For proton lab energies around 1 GeV, the Kerman-Kisslinger model gives alignments that are characteristically different from the predictions of the simple exchange model, showing that the presence of the in the deuteron has a significant effect at these energies.
