Abstract: Reflection-asymmetric octupole structures are studied in the transitional nucleus 221Th. There are several modifications at intermediate spins to the previously reported yrast structure. The level scheme is considerably extended with yrast states up to (39/2) established. A nonyrast octupole structure is identified which does not constitute a parity doublet with the yrast states, unlike those observed in some of the heavier odd-A Th isotopes. This is attributed to the low K value of the ground-state configuration. The strength of octupole correlations and quadrupole collectivity is found to vary with spin. The role of nucleon alignments in influencing collective properties is explored through cranking calculations incorporating octupole deformation. © 2013 American Physical Society.
