SPECTROSCOPY OF 1F-2P NUCLEI WITH DIRECT (D-ALPHA) AND (D,P) REACTIONS .2. CU64

Levels of Cu64 were studied with 12.08-MeV deuterons via the Zn66(d,α) reaction with 11-12-keV resolution and the Cu63(d,p) reaction with 7-8-keV resolution. About 85 levels were identified for Eex≤3 MeV, i.e., 35 more than reported in the most recent literature. Zn66(d,α)Cu64 angular distributions were obtained over the range 15°≤θ≤90°, and L values were extracted from comparison with distorted-wave Born-approximation (DWBA) calculations which incorporated finite-range and nonlocality corrections as well as microscopic form factors. Good agreement was found between the observed and calculated angular distributions. Cu63(d,p)Cu64 angular distributions were obtained over the range 8°≤θ≤50°, and l values and spectroscopic factors were extracted from the comparison with DWBA calculations which included finite-range and nonlocality corrections and spin-orbit coupling for the bound neutron. It was possible to make unique 1+ and 3+ assignments for many levels from the recognition of L=0 transfers, L mixing in (d,α) transitions, and overlap between (d,α) and (d,p) Jπ limits. Good agreement in Jπ assignments was found between the present work and (n,γ) work for almost all levels below 1-MeV excitation. © 1969 The American Physical Society.
