Abstract

The (d, t) and (d, He3) reactions on targets of C12, O16, Mg24, and Ca40 leading to prominent low-lying analog states in the residual nuclei have been studied by measuring differential cross sections and vector analyzing powers. The cross section angular distributions at best exhibit only a weak sensitivity to the transferred angular momentum while the vector analyzing powers are strongly sensitive to the transferred angular momentum and provide a useful signature of the j transfer. Zero-range distorted-wave Born-approximation predictions describe the σ(θ) angular distributions quite well for the lighter targets while they only partially succeed in describing the Ay(θ) for the lighter targets. An improved distorted-wave Born-approximation description was obtained for the Ca40 target. Some sensitivity to the choice of optical parameters in the distorted-wave Born-approximation analysis, particularly obvious in the Ay(θ) predictions was seen. Values of extracted spectroscopic factors were generally consistent with those reported in other work (both experimental and theoretical).
