| Abstract: | Excited states in odd–odd 126I have been studied via the heavy–ion induced fusion–evaporation reaction 122Sn(11B,5n2p) at beam energies of 55 and 60 MeV with beams provided by the HI–13 tandem accelerator of CIAE in Beijing.A level scheme consisting of 20 new γ transitions assigned to 126I is established.The assignment of the established level scheme to 126I is based on the observed coincidences between the newly identified γ–transitions and two previously known cascade γ transitions feeding the ground state of 126I, and supported by a cross measurement using the 124Sn(7lI,5n) reaction performed at UTTAC,Japan.The observed structures of 126I at high spins show typical properties of collective rotation in a deformed nucleus. their possible configurations are discussed briefly on the basis of knowledge from the neighboring nuclei. |
