Lifetime of the K^π = 8^- isomer in the neutron-rich nucleus ¹⁷⁴Er, and N = 106 E1 systematics

NUCLEAR REACTIONS ¹⁷⁶Yb(¹³⁶Xe, X), E=840 MeV; measured Eγ, Iγ, γγ-coin, isomer half-life. ¹⁷⁴Er; deduced levels, J, π, E1 hindrance factors, configurations. Discussed systematics of E1 hindrance factors and E(4+)/E(2+) for even-even Er, Yb, Hf, W, Os, Pt, Hg and Pb nuclides. K-mixing calculations in the framework of particle-rotor model.
