Effect of Residual p-n Interaction on Crossing Frequency Delay of 1/2 ~-[541]Band

Key words: 
• residual p-n interaction /
• crossing frequency /
• delay

Abstract: We estimated the effect of residual p-n interaction on the crossing frequency delay of the 1/2~(-)\ band of four odd-Z nuclei through the empirical method. The result shows that about half of the shift in crossing frequency in the 1/2~-\ band is the effect of residual p-n interaction. The residual p-n interaction plays a very important role in the crossing frequency delay of the 1/2~(-)\ band.
