Abstract

The $^{165} Ho (γ, x n)$ reaction cross section has been measured with a 100 keV bin in the range from threshold up to 23 MeV. The analysis of the yield curve is based on the least structure solution using the thick-target forward-direction bremsstrahlung spectrum. Finally, taking into account the Nilsson level scheme, the total E1 photoabsorption cross section was computed and compared with the present data and other published experimental data.

Giant resonance in the total photoabsorption cross section of Z ≈ 90 nuclei
1976, Nuclear Physics, Section A
Total photoabsorption cross sections of ²³²Th, ²³⁵U, ²³⁸U and ²³⁹Pu have been measured in the giant resonance region by the absorption method. Measured cross sections were approximated by two Lorentz lines. Lorentz line parameters, integrated cross sections, deformation parameters and quadrupole moments are given. The analysis of the nuclear optical anisotropy evolution with the increase of Z shows that Z ≈ 90 nuclei seem to be transitional, similar to N ≈ 90 nuclei. A comparison of experimental cross sections with dynamic collective model calculations has been performed. The evidence that quadrupole photoabsorption occurs in the 20–25 MeV energy region is also presented.
