Universal Effective Charges in the $s d$ and $f p$ Shells

T. H. Ogunbeku, J. M. Allmond, T. J. Gray +79

The 247-keV state in $^{54}$ Sc, populated in the $β$ decay of $^{54}$ Ca, is reported here as a nanosecond isomer with a half-life of 26.0(22) ns. The state is interpreted as the $1…

Reduction in nuclear size and quadrupole deformation of high-spin isomers of 127,129In

A. R. Vernon, C. L. Binnersley, R. F. Garcia Ruiz +29

We employed laser spectroscopy of atomic transitions to measure the nuclear charge radii and electromagnetic properties of the high-spin isomeric states in neutron-rich indium isot…

Refined topology of the N = 20 island of inversion with high precision mass measurements of $^{31 - 33}$ Na and $^{31 - 35}$ Mg

E. M. Lykiardopoulou, C. Walls, J. Bergmann +30

Mass measurements of $^{31 - 33}$ Na and $^{31 - 35}$ Mg using the TITAN MR-TOF-MS at TRIUMF's ISAC facility are presented, with the uncertainty of the $^{33}$ Na mass reduced by over two…
