内容記述 |
Nuclear resonance fluorescence (NRF) measurements on natural Hf and natural W were performed using linearly polarized quasi-monochromatic gamma-ray beams generated by laser Compton scattering (LCS) at the high intensity gamma-ray source (HIgS) facility of Duke University. The gamma-ray beams, in the 2.4-3.2 MeV energy range, excited multiple nuclides simultaneously via NRF. In total, we observe 29 dipole transitions. The spin and parity of the observed levels can be determined from the intensity ratio of gamma-rays scattered parallel to the polarization plane of the incident gamma-rays and perpendicular to the polarization plane of the incident gamma-rays. The resonance widths as well as the spin-parity of these levels were determined. In this presentation, we report the experimental results of the magnetic dipole strength for the investigated isotopes. |
