Abstract：
The observation of multi-band structure in nucleus ¹⁸⁵Pt reported recently,once again raises the open question about whether the alignment of proton h _9/2pair or neutron i _13/2pair should be responsible to the backbending in five band.Blocking experiments prefer the proton h _9/2pair while the Total Rothian Surface calculation supports neutron i _13/2pair.Based on the analysis of assumptions implied in both approaches,a new theoretical calculation which includes the dynamic effect of band crossing is presented.Such a calculation indicates that the alignment of proton h pair should be the main cause for the observed backbendings.
