Evolution of octupole collectivity in ²²¹Th

NUCLEAR REACTIONS ²⁰⁸Pb(¹⁶O, 3n), E=86 MeV; measured Eγ, Iγ, γγ-coin, γγ(θ)(DCO) using INGA array at TIFR facility. ²²¹Th; deduced high-spin levels, J, π, bands, multipolarity, moment of inertia plots, reflection-asymmetric octupole structures, intrinsic electric dipole moment. Systematics of energy splittings between positive and negative-parity states in odd-A (A=219-225) Th nuclei. Comparison with Woods-Saxon cranking calculations including octupole deformation.
