A sequence of nine almost equidistant quadrupole transitions is observed in 137Nd. The sequence represents
an extremely regular rotational band that extends to a spin of about 75/2 and an excitation energy of ≈4.5 MeV
above yrast. Cranked mean-field calculations of the Nilsson-Strutinsky type suggest an oblate shape for the band.
They reproduce the observed I(I + 1) dependence of the rotational energy whereas predicting a pronounced
decrease in the deformation, which is the hallmark of antimagnetic rotation.

F.; Stryjczyk, M.; Van Duppen, P.; Vinals, S.; Virtanen, V.; Warr, N.; Wrzosek-Lipska, K.; Zielinska, M. (American Physical Society, 2020)There is sparse direct experimental evidence that atomic nuclei can exhibit stable “pear” shapes arising from strong octupole correlations. In order to investigate the nature of octupole collectivity in radium isotopes, ... -
