Times Cited Count:0 Percentile:0.00(Nuclear Science & Technology)In recent years, research has been advanced on lead-cooled fast reactors and accelerator drive systems, and it is required to improve the accuracy of the neutron capture cross section of Pb isotopes. Although Pb has a small natural abundance, it is of importance because it produces the long-lived radionuclide
Pb (17.3 million years) by neutron capture reaction. However, it is difficult to measure its cross section by a conventional activation method using a nuclear reactor because the induced radioactivity of
Pb is weak. Hence, the cross-section measurement was performed by applying mass spectrometry. This presentation gives the details of the experiment and the results obtained in the neutron capture cross-section measurement of
Pb using mass spectroscopy.

Times Cited Count:5 Percentile:51.80(Physics, Nuclear)Low-lying dipole transitions in Pb were measured via nuclear photon scattering using a quasi-monochromatic, linearly polarized photon beam. The electric (
) and magnetic (
) dipole strengths were extracted for excitation energies up to 6.8 MeV. The present (
,
) results, combined with (
,
) data from the literature, were used to investigate the
and
photoabsorption cross sections near the neutron separation energy by comparison with predictions of the particle-vibration coupling on top of the quasi-particle random phase approximation (PVC+QRPA).

Times Cited Count:11 Percentile:62.84(Physics, Nuclear)The dipole strength distribution of Pb was investigated via a nuclear resonance fluorescence experiment using bremsstrahlung produced with an electron beam at a kinetic energy of 10.5 MeV at the linear accelerator ELBE. We identified 88 states resonantly excited at energies from 3.7 to 8.2 MeV. The photo-absorption cross sections were extracted from the measured scattering cross sections and the branching ratios. The present (
,
) data combined with (
,
) data from the literature were used as an input to the statistical calculation code CCONE to evaluate the neutron capture cross section of the unstable
Pb nucleus.
