主　　题：signature partner band multiple antimagnetic rotation classical particle-rotor model 

摘      要：The positive-parity signature partner bands in^(103,105)Pd and^(109)Cd nuclei are investigated using the classical particle-rotor *** on the systematic study of neighbouring nuclei,the signature partner bands of ^(105)Pd are assigned to theπ(g^(-4)_(9/2))■ν(g7/2h^(2)_(11/2))configuration,and this assignment is also supported by the present ***,the calculated$B(E2)$values of such bands of ^(105)Pd reproduce the experimental values well and exhibit a decrease with increasing angular momentum,suggesting that these two bands may originate from antimagnetic *** signature partner bands are also found in the neighboring^(103)Pd and^(109)Cd *** properties of both bands are in general agreement with the fingerprints of antimagnetic rotation,and thus the signature partner bands of^(103)Pd and^(109)Cd are suggested to be candidates for the multiple antimagnetic rotational bands of ^(105)*** addition,the evolution of the two-shears-like mechanism for possible multiple antimagnetic rotational bands in^(103,105)Pd and^(109)Cd nuclei is examined by investigating the orientation of the angular momenta.
