主　　题：chiral doublet bands particle rotor model cranking relativistic mean-field theory high-j particle hole configuration 

摘      要：Positive-parity doublet bands were reported in *** on these,we discuss the corresponding experimental characteristics,including rotational alignment,and re-examine the corresponding configuration *** self-consistent tilted axis cranking relativistic mean-field calculations indicate that the doublet bands are built on the configurationπh11/2νh11/2^-*** adopting the two quasiparticles coupled with a triaxial rotor model,the excitation energies,energy staggering parameter S(I),B(M1)/B(E2),effective angles,and K plots are discussed and compared with available *** obtained results support the interpretation of chiral doublet bands for the positive-parity doublet bands in 120I,and hence identify this nucleus as the border of the A≈130 island of chiral candidates.
