Abstract

Two regular dipole gamma-ray cascades have been observed in 194Pb. A comprehensive level scheme related to these structures has been built and first members of rotational bands built on K = 8 and K = 11 two-proton oblate states have been identified. From the excitation energies, spin values, behaviours of the moments of inertia and alignments, and from the comparison with the isotone 192Hg, multiparticle configurations can be attributed to three high-spin structures of 194Pb built respectively on the 4966keV, 4334keV and 6198keV levels: {pi9/2[505]pi13/2[606]}{nui13/2}2, {pi9/2[505]pi13/2[6061}{nuf5/2nui13/2}, {pi9/2[505] pi13/2[606]} {nuf5/2(vi13/2)3}. Within this interpretation, the regular dipole bands correspond to the presence of two or three i13/2 decoupled neutrons.
