Abstract：
The high-spin states of ²⁰⁶At have been studied in the ¹⁹⁷An ( ¹²C, 3n) ²⁰⁶At reaction at ¹²C energies from 60 to 80 MeV using technique of in-beam γ-ray spectroscopy. Measurements of Tray excitation functions, γ-γ-t coincidences, and y-ray angular distributions were performed. A level scheme for ²⁰⁶At, including a 10 ^－isomer with a measured half-life of 908±400 ns, was established for the first the. The characteristics of the 10 ^－isomers in doubly edd ²⁰⁶At nuclei were stressed.
