Abstract：
πh_9/2 alignment in Pt even isotopes has calculated and discussed systematically.It is found that Δhω_c≡hω_c(πh_9/2)－hω_c(νi_13/2) approches the minimum,about 75keV.for 78¹⁸⁴Pt106 by using modified Nilsson's parameters κμ.This result is in agreement with the experimental evidence that the big up-bend observed in the yeast band of ¹⁸⁴Pt is caused by the lose alignment of πh_9/2 and νi_13/2.While the standard Nilsson's κμ can not give out such a result.The problem of the orderof πh_9/2 and νi_13/2 alignments needs further investigation.The pretical prediction about the πh_9/2 alignment frequency for neighboring Pt even isotopes should be checked by new experiments.
