Cross sections and vector analyzing powers for the (d,t) reaction on /sup 68/Zn, /sup 64/Ni, /sup 57/Fe, and /sup 53/Cr

Differential cross sections and vector analyzing powers have been measured for (d,t) reactions induced on /sup 68/Zn and /sup 64/Ni at E/sub d/=12.0 MeV and on /sup 57/Fe and /sup 53/Cr at E/sub d/=11.0 MeV. Transitions with l=0, 1, 2, 3, and 4 were observed. The analyzing power measurements for l=1 transitions exhibit a strong, systematic dependence on Q value, in addition to the expected j dependence. Distorted-wave Born approximation calculations generally do not reproduce the (d,t) analyzing power data quantitatively, but do account qualitatively for the observed Q dependence. A conclusive analysis of data for the odd-A targets, aimed at determining the relative contributions of different j values to mixed-j transitions, has been possible only in those cases where empirical ''calibration curves'' for the analyzing powers could be drawn from results of single-j transitions of appropriate l, j, and Q. A number of previous spin and parity assignments are confirmed and two new definite assignments are made on the basis of the present data.
