Low-spin spectroscopy of 205Pb and 207Pb by the thermal neutron capture reactions: 204Pb(n,gamma)205Pb and 206Pb(n,gamma)207Pb
We propose to perform a low-spin gamma-ray spectroscopy study of 205Pb and 207Pb by employing the gamma-gamma coincidence technique, making use of the neutron capture reactions: 204Pb(n,gamma)205Pb and 206Pb(n,gamma)207Pb, respectively, and the FIPPS germanium array at ILL. The setup will consist of 8 HPGe clover detectors, in annular geometry around the target. The reactions will populate a large number of excited states of 205Pb and 207Pb up to the neutron binding energies (both at 6.7 MeV), within a few units of spin. The new data on these three- and one-valence-neutron-hole nuclei (with respect to the doubly magic core 208Pb) will provide a testing ground for various theoretical approaches.
