Resolving anomalous collectivity in the to transition of Fe

J. A. Woodside, B. J. Coombes, A. E. Stuchbery +7

The low-excitation states of atomic nuclei in the region around the shell closure are generally well described by the shell model. Most experimental observables in the…

Coulomb excitation of Te: Emerging collectivity and persisting seniority structure in the level

M. Reece, B. J. Coombes, A. J. Mitchell +9

The low-lying energy spectra of even-even tellurium isotopes near midshell have long been interpreted as `textbook' examples of vibrational collective motion. However, in many case…

Direct measurement of hexacontatetrapole, γ decay from Fe

T. Palazzo, A. J. Mitchell, G. J. Lane +11

The only proposed observation of a discrete, hexacontatetrapole () transition in nature occurs from the T = 2.54(2)-minute decay of Fe. However, there are confl…
