Abstract

The (d,t) and (d,/sup 3/He) reactions on targets of /sup 12/C, /sup 16/O, /sup 24/Mg,and /sup 40/Ca leading to prominent low-lying analog states in the residual nuclei have been studies 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 sigma (theta) angular distributions quite well for the lighter targets while they only partially succeed in describing the A/sub y/(theta) for the lighter targets. An improved distorted-wave Born approximation description was obtained for the /sup 40/Ca target. Some sensitivity to the choice of optical parameters in the distorted-wave Born approximation analysis, particularly obvious in the A/sub y/(theta) predictions was seen. Values of extracted spectroscopic factors were generally consistent with those reported in other work (both experimental and theoretical).
