Polarization effects in light nuclei

Three topics are discussed. Measurement of the deuteron D state is addressed. Experimental and theoretical results for the asymptotic D- to S-state ratio of the deuteron wave function have converged to about 0.0260. This suggests that P sub D/ greater than or equal to 3.5%. The discussion on the three-nucleon system centered on the present state of agreement between experimental results and results calculated with the Faddeev equations. Polarization and analyzing power in the 15N(p,n)15O reaction were considered. Rather large P-A differences were found in the region of 5 to 9 MeV. These differences can be nicely explained by microscopic shell-model calculations that include a noncentral nucleon-nucleon interaction and isospin mixing. 3 figures
