O(6)-symmetry breaking in theγ-soft nucleusXe126and its evolution in the light stable xenon isotopes

“…The previously known B(E2; 2 + 1 → 0 + 1 )=0.152(5) e 2 b 2 value from Ref. [23] sets the absolute scale. The energy loss of the beam inside the target (∼40 MeV) was taken into account.…”

“…The energy resolution achieved here did not permit to resolve these two doublets. Therefore, the intensities of each doublet were fitted and the previously known branching ratios [23] were used to obtain the individual respective intensities.…”

“…The contributions of known transitions that were not observed (e.g. due to their too low energy or the presence of contaminants), have been determined from previously published branching ratios [23].…”

“…Besides the statistical uncertainties the final results in Table I also include uncertainties from all quantities varied or constraining the e These transitions are doublets, the individual intensities have been separated using the known branching ratios taken from Ref. [23].…”

“…h Determined through the branching ratio from Ref. [23]. i This transition was observed only in coincidence spectra.…”
