/sup 206/Pb(. cap alpha. ,d)/sup 208/Bi at 48 MeV
The /sup 206/Pb(..cap alpha..,d)/sup 208/Bi reaction was investigated at 48.2 MeV with about 25 keV resolution. Angular distributions were obtained for 48 levels at excitation energies up to 5 MeV. Many previously unknown levels were seen and most seem to have two-particle--two-hole structure and spins above 6; however, the relatively structureless angular distributions permit only approximate L assignments. Transitions to six low-lying one-particle--one-hole states were analyzed in detail. Distorted-wave Born approximation predictions agreed with the observed angular distributions, but the absolute cross sections computed from published /sup 206/Pb and /sup 208/Bi wave functions are generally larger than observed, particularly those for the J/sub max/ states. Contributions of the dominant two-step sequential stripping channels to the one-step results were investigated. They were important and gave varying amounts of enhancement for all six levels. The observed quenching of the J/sub max/ cross sections was not reproduced.
