Evidence for triaxial deformation near N=86: Collective bands in 152,153Dy and 153Ho
Abstract
The N=86,87 isotopes of dysprosium and holmium have been investigated using the Eurogam II γ-ray spectrometer. A new collective rotational band has been observed in 153Ho and the previously observed νi13/2 band in 153Dy has been extended to much higher spin. Comparing these bands and similar bands in 152Dy with the collective bands in the N=90 isotopes of Dy, Ho, and Er suggests that the first h11/2 proton crossing is not observed at N=86,87. …
