Direct measurement of hexacontatetrapole, $\text{E6}$ γ decay from ${}^{\text{53m}}$Fe

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

The only proposed observation of a discrete, hexacontatetrapole ($E6$) transition in nature occurs from the T${}_{1/2}$ = 2.54(2)-minute decay of ${}^{53m}$Fe. However, there are confl…
