Angular distributions and Q values were determined for proton groups from (d.p) reactions with isotopically enriched targets of Zn/sup 64/, Zn/sup 66/ , Zn/sup 67/, and Zn/sup 68/. The incident deuteron energy was 10 Mev. The angular distributions were fitted by Butler curves, from which values of l/sub n/ were determined. where l/sub n/h is the orbital angular momentum of the captured neutron. The fits were only fair, presumably because the Butler theory cannot be expected to give good fits at Z = 30 without modification. In addition, several peaks are evidently superpositions of closely spaced, unresolved groups with different l/sub n/. Well-resolved empirical distributions which appear to correspond to l/sub n/ = 0, 1, 2, 3, and 4 were observed; these serve to indicate in which direction the Butler curves should be shifted, thus increasing confidence in the correctness of the values of l/sub n/ wbich were assigned. For Zn/sup 64/(d,p) we find Q = 5.71 Mev with l/sub n/ = 1 and 3, Q = 4.89 Mev with l/ sub n/ = 1 and 3 or 4, Q=4.43 Mev with l/sub n/= 2, Q = 3.86 Mev with l/sub n/ = 0. and Q =3.31 Mev with l/sub n/= perhaps 2 and 4. For Zn/sup 66/(d,p) the results were Q = 4.76 Mev with l/sub n/ = 1 and 3, Q = 4.38 Mev with l/sub n/ = 1 and 3 or 4, Q = 3.85 Mev with l/sub n/ = 2, and Q = 3.15 Mev with l/sub n/ uncertain. for Zn/sup 67/(d,p) we find Q = 8-01 Mev with l/sub n/ = 3, Q=6.90 Mev with l/sub n/ = 1, Q =6.13 Mev with l/sub n/ unknown, and Q = 4.52 Mev with l/sub n/ = perhaps 1 and 3. For Zn/sup 68/ (d,p) the results were Q = 4.22 Mev with l/ sub n/ = 1, Q = 3.78 Mev with l/sub n/ =4, and Q =3.40 with l/sub n/ = 2. (auth)
