Resolve the discrepant B(E2) measurements for 28Ne

Determine the source of the unresolved discrepancy between the earlier experimental measurement and the other available data for the reduced electric quadrupole transition probability B(E2) in 28Ne.

Background

The paper compares calculated B(E2; 2₁⁺ → 0₁⁺) strengths for even-even neon isotopes with available experimental data. Although the overall isotopic trend is reproduced, the calculation overestimates the value for 28Ne. The authors note that an earlier experimental measurement reported an even larger B(E2) value than the data set used for comparison, leaving an unresolved discrepancy between the two experimental data sets.

Resolving this discrepancy is necessary for establishing the experimental B(E2) systematics of neutron-rich neon isotopes and for assessing the reliability of theoretical descriptions of quadrupole collectivity near the N = 16 subshell region.

References

An earlier experimental measurement yielded an even larger B(E2) for 28Ne [45], and the discrepancy between the two data sets remains unresolved.
