Abstract：
The reaction of ¹³⁹La( ⁸²Se, x) ¹³⁶Ba was used in this experiment. The nuclide ¹³⁶Ba was produced via the transfer reaction channel. Some new γ rays of ¹³⁶Ba were measured and a new isomer state at 10 ⁺was observed. The half life of this isomer is 94ns based on its time spectrum. According to the intensities of gamma transition and gamma-gamma coincidence relationship, the scheme of ¹³⁶Ba is suggested.
