Abstract：
High spin states in ¹⁰⁶Ag have been studied using the ¹⁰⁰Mo(¹¹B,5n)¹⁰⁶Ag reaction at a beam energy of 60MeV at HI-13 tandem accelerator in China Institute of Atomic Energy. The γ-γ coincidences were measured using 15 HPGe detectors with Compton suppressed shield. By analyzing the γ-γ coincidence and their DCO ratios, new level scheme of ¹⁰⁶Ag has been presented. 26 new γ were found compared with previous level scheme. Experimental evidences for chiral doublet bands built on πg_9/2⊙υh_11/2 configuration in ¹⁰⁶Ag are briefly discussed. But 2h difference in alignments is too large to interpret as chiral doublet bands.
