- The study of the scattering of polarized deuterons yielded improved optical potentials, particularly spin--orbit and tensor potentials. Extensive measurements of vector and tensor analyzing powers for (d,p), (d,n), and (d,t) reactions corrected several J/sup ..pi../ assignments, revealed deficiencies in DWBA calculations, showed some interesting systematics, gave evidence for two-step processes, and demonstrated important deuteron D-state effects. New vector and tensor polarimeters permitted routine beam-polarization checks. Analyzing powers measured to +-- 2 x 10/sup -4/ for p--p scattering at E/sub p/ = 10 MeV gave model-independent phase-shift analysis for E/sub p/ less than 25 MeV. Accurate analyzing powers and cross sections for p + ..cap alpha.. suggested a D-state component in the ..cap alpha.. particle. Precise absolute cross sections for several (n,p) and (n,..cap alpha..) reactions resulted from associated-particle measurements. Instrumentation for (p,n) and (..cap alpha..,/sup 8/Be) studies at intermediate energies is underway. Extensive isospin-forbidden cross sections gave level parameters for isospin-mixed /sup 18/F states and implied intermediate structure and ''bridge'' states. Level parameters for /sup 18/F unnatural-parity states resulted from /sup 16/O(d vector,..cap alpha../sub 3/)/sup 14/N(J = 0/sup -/) measurements. Radiative capture and scattering of ..cap alpha..'s by /sup 14/N, /sup 16/O, and /sup 20/Ne gave data about /sup 18/F, /sup 20/Ne, and /sup 24/Mg. Ion-source development work included a new type polarized source, a new sputter source, and a device for beam emittance measurements. (RWR)
