The higher-lying states in /sup 205/Pd (E/sub x/ > or = 2.57 MeV) are examined by means of the /sup 204/Pb(d, p) transfer reaction at incident energies of 13.0 and 20.0 MeV. In order to extract a reliable set of spectroscopic factors, a consistent set of distorted-wave Born approximation parameters is derived from analyses of new /sup 208/Pb(d, p) data at E/sub d/ = 13.0 MeV, and by reanalysis of earlier /sup 206//sub,//sup 208/Pb(d, p) data. By avoiding proton optical parameters based on data in an energy region later found to contain resonances, and by using a deuteron potential which corrects for deuteron breakup, /sup 208/Pb(d, p) spectroscopic factors consistent to +- 15% are obtained. The improved distorted-wave Born approximation parameters are used to assign orbital angular momentum (l/sub n/) values to a majority of 110 new levels in /sup 205/Pb, most of them heretofore unknown. Significant fractions of the 1i/sub 11///sub 2/ and the 1j/sub 15///sub 2/, and the majority of the 2g/sub 9///sub 2/, 3d/sub 5///sub 2/, 4s/sub 1///sub 2/, 2g/sub 7///sub 2/, and 3d/sub 3///sub 2/ single-particle strengths are located. These strengths are found to be concentrated about the energy centroids. A previous theoretical calculation of spectroscopic strengths compares poorly with the experimental values. (AIP)
