摘要：
The Pb208(p,d)Pb207 reaction has been used with 20.00- and 22.00-MeV proton beams from the Yale MP tandem accelerator to study the low-lying neutron-hole levels of Pb207. The finite-range, nonlocal distorted-wave Born-approximation (DWBA) analyses of the experimental (p,d) angular distributions indicate that the 12-(3p12-1) ground state, the 52-(2f52-1) 570-keV level, the 32-(3p32-1) 894-keV level, and the 132+(li132-1) 1634-keV level are almost pure single-neutron-hole levels in the Pb208 core. The 2f72 neutron-hole strength, and particularly the 1h92 neutron-hole strength, may be somewhat fragmented, although the 72-(2f72-1) 2334-keV level and the 92-, (1h92-1) 3430-keV level represent large fractions of their respective sum-rule neutron-hole strength. No evidence was found for j dependence in the Pb208(p,d) angular distributions at Ep=20.00and 22.00 MeV. © 1969 The American Physical Society.
