First evidence ofγcollectivity close to the doubly magic coreSn132

et al. 2016

The138 Te and 140 Xe nuclei have been reinvestigated using prompt γ-ray data from spontaneous fission of 248 Cm, collected with the EUROGAM2 Ge array. γ bands have been identified in both nuclei. The γ band observed in 138 Te, a nucleus with only 6 valence nucleons, indicates the presence of collectivity very close to the doubly-magic 132 Sn core. Such band is even more pronounced in 140 Xe, the N=86 isotone of 138 Te. The newly observed bands are interpreted within the shell model, which reproduce well the γ collectivity at N=86.

“…From theoretical point of view it has been suggested that the reduction of the 2 + 1 excitation energy beyond 132 Sn is caused by a stabilization going from sphericity in 136 Te [13,14], with a transition in 138 Te [15] to a soft prolate deformation in 140 Te [16]. Instead, a smooth behavior of the excitation energy ratios E x (4 + 1 )/E x (2 + 1 ) is observed in 138,140 Te [17,18]. Also, the unexpectedly low B(E 2; 2 + 1 → 0 + 1 ) transition strength in 136 Te [19] triggered more investigations on the collectivity and the evolution of deformation both from theoretical and experimental points of view.…”

“…The first calculation uses the 'optimal' spin scaling factor α discussed above and the improved 2015 RIPL-3 database. The second calculation supplements RIPL-3 with discrete level data for 104 Zr [21] and 138 Te [22,23]. The third calculation increases the spin scaling factor α by about 10%.…”

Using CGMF to estimate corrections for fission yields measured via γ-ray spectroscopy

et al. 2020

View full text Add to dashboard Cite

Fission product yields have been inferred using γ-ray spectroscopy for several decades. Typically, these efforts have focused on even-Z even-A fission products as their nuclear structure are less complicated. To further simplify the situation, it is often assumed that no side-feeding to the ground-state occurs and multiplicity cuts have a negligible effect on the inferred yields. Using CGMF, a Hauser-Feshbach statistical decay model for the primary fission fragments, we estimate the impact of these assumptions and determine corrections for specific fission product yields. We report on these corrections and investigate their sensitivity to various nuclear parameters, specifically the spin distribution of the fission fragments and the assumed nuclear structure. Our results indicate that even in the simplest of cases, say the 2+ → 0+ transitions in even-Z even-A fragments, average level corrections are on the order of 75%.
