dc.description.abstractThe lifetimes of the excited states belonging to the chiral-candidate doublet bands built on the ?h11/2 - ?h11/2-1 configuration in La130 have been measured by applying the Doppler-shift attenuation method and the in-beam fast timing technique. Excited states were populated in the Sb121(C12,3n) reaction at a bombarding energy of 54 MeV. The 7+ bandhead of the yrast band was identified as an isomeric state with a lifetime of ?(7+)=0.38(7)ns. Similar reduced transition probabilities B(M1) and B(E2) were found for the states with the same spin in the partner bands. The results revealed an even-odd spin dependence in the B(E2) values, whereas the B(M1) values vary nearly monotonically with increasing spin. The experimental properties of the doublet bands in La130 are compared with theoretical calculations done in the frame of the two-quasiparticles-plus-triaxial-rotor model. The static chirality is not supported by the obtained data; however, chiral vibrations cannot be excluded. © 2018 American Physical Society.en_US
