Evolution of collectivity in the N=100 isotones near ¹⁷⁰Yb

NUCLEAR REACTIONS ¹⁶⁸Er(α, 2n), E=27 MeV; measured Eγ, Iγ, level half-lives by γγ(t) using electronic γ-γ fast-timing technique using HPGe detectors and LaBr3(Ce) detectors at Cologne 10 MV FN-Tandem accelerator. ¹⁷⁰Yb; deduced levels, yrast band, B(E2). Comparison with confined beta soft (CBS) model calculations, X(5) predictions, and with previous experimental results. Systematics of ground state band energies and B(E2) in N=100 isotones of ¹⁶⁸Er, ¹⁷⁰Yb, ¹⁷²Hf, ¹⁷⁴W and ¹⁷⁶Os.
