The 207Pb(d, p)208Pb reaction with high resolution
1973
Abstract The reaction 207 Pb(d, p) 208 Pb has been studied at E d = 18.0 MeV using the MPI Heidelberg Emperor tandem accelerator and multiple-gap spectrograph. The average resolution of 18 keV was better than previous measurements, and this, combined with the long beam exposure, allowed many finer details of the neutron particle-hole structure of 208 Pb to be examined. In all, 45 levels were seen up to E x = 6.3 MeV, many of which had never been seen before. A DWBA analysis of the stripping transitions angular distributions is made, and values of (2 J + 1) S ij , energy centroids, and summed strengths are given. An interesting cluster of 1i 11 2 and 2g 9 2 levels at E x ≈ 4.2 MeV are resolved and are compared to recent isobaric analog state data. A search for weak stripping strength to known pairing vibrations in 208 Pb gave essentially negative results and points to the need for improved ultra-resolution measurements.
