On the enhanced E1 transitions in the K = 3/2 parity doublet band in 223Ra
RADIOACTIVITY 223Fr(β-)[from 223Rn]; measured β-decay of (3/2)- and (5/2)- states (50 and 80 keV) Eγ, Iγ(t) using BaF2 crystal for timing and two Ge, Eβ, Iβ(t) using ΔE NE111A, βγ-coin; deduced time-delayed βγ(t) spectrum, T1/2, B(E1), B(E2), B(M1) for K=3/2 band states below 250 keV, intrinsic electric dipole moment D0; calculated T1/2, γ transition probabilities, B(E1), B(E2), B(M1), average electric dipole moment for 223,224Ra (and compared with available data for Ra isotopes), quadrupole and octupole vibration energies in 222,224Ra, structure of intrinsic states.
