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_9/2 pair or neutron i_13/2 pair should be responsible to the backbending in five band.Blocking experiments prefer the proton h_9/2 pair while the Total Rothian Surface calculation supports neutron i_13/2 pair.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.
