Measurement of theGd157(n,γ) react

Constraining the calculation of U234,236,238(n,γ) cross sections with measurements of the Ullmann1, Kawano2, Baramsai3 et al. 2017Phys. Rev. CSelf Cite

“…First, attempts (not shown) to fit the spectra with a single Lorentzian scissors-mode resonance structure were not very successful, and the two-Lorentzian structure determined in the Oslo results seems to be required. Second, contrary to the situation in the rareearth region [26][27][28], our calculations cannot conclusively determine the character of the resonance structure between 2 and 3 MeV. This is a consequence of the high NLD for levels with both parities.…”

“…In our limited search, we started by using for the E1 component the Modified Generalized Lorentzian form (MGLO) [26] with k = 3 and fixed temperature T = 0.5 MeV. This model provided a good description of the MSC spectra in well-deformed Gd nuclei [26][27][28]. The GDR parameters were taken from fits to 239 Pu photoabsorption cross section data in ref.…”

Low-Energy Enhancement of Magnetic Dipole Radiation

“…In fact, 90 Zr and the Mo isotopes discussed in the present work as well as the Fe, Ni, and Cd isotopes, for which the low-energy enhancement was observed [15][16][17], belong to these regions. On the other hand, 117 Sn [47], 158 Gd [48], and the Th, Pa isotopes [14], for which no low-energy enhancement was observed, lie outside these regions. In Ref.…”

Estimation of M1 scissors mode strength for deformed nuclei in the medium- to heavy-mass region by statistical Hauser-Feshbach model calculations

“…See Ref. [43] for the details of the calculation. The calculated two and three step cascade γ-ray spectra from 156 Gd and 157 Gd are compared with the DANCE experimental data in Figs.…”
