²²⁷Ac evaluated by B. Singh, I. Ami, α. Chakraborty, S. Kumar, M. Latif and d. Yang.

²²⁷Ac lies at the border of the octupole-quadrupole and pure quadrupole deformation regions. 1983Sh16 interpreted this nucleus as having a core with a "soft " octupole deformation (1990Ja11). The presence of parity doublet rotational bands, and also of K=1/2 rotational bands with decoupling parameters having opposite signs, suggests a stable octupole deformation for ²²⁷Ac (1987Le05). The level structure, (α,t) spectroscopic factors, and the ground state magnetic and quadrupole moments, have been interpreted in terms of a stable octupole deformation with ε₃≈0.1 (1988Le13,1983Sh16). It should be mentioned, however, that the experimental (α,t) spectroscopic factors of 1988Ma18 agree with theoretical values based on a quadrupole deformation only.

Levels: Band assignments: parity doublet band assignments are from 1990Ja11. Although octupole deformations are small in this region, the states are not fully characterized by single Nilsson orbitals. Single-particle orbitals, however, are used here to label states rather than to accurately describe their detailed configurations
