偶质量核和奇质量核谱统计的配对效应

Pairing Effect on Spectral Statistics of Even and Odd Mass Nuclei

H. Sabri, B. Rashidian Maleki, J. Fouladi, N. Fouladi, M. A. Jafarizadeh

摘要:

利用核密度和极大似然估计技术,研究了核系统谱统计中配对的相互作用,重点是最近邻间距分布。利用现有的34 < A < 206质量区偶、奇质量核低能级的经验数据编制了不同的序列。与奇质量核相比,偶数质量核明显偏离更规则的动力学,并且有建议认为由于未闭合的质子壳层对更混乱的动力学产生影响。

英文摘要:

The interplay of pairing is explored for the spectral statistics of nuclear systems with emphasis on the nearest neighbor spacing distributions by employing the kernel density and maximum likelihood estimation techniques. Different sequences prepared by all the available empirical data for low-lying energy levels of even and odd-mass nuclei in the 34 < A < 206 mass region. A deviation to more regular dynamics is apparent for even-mass nuclei in compare to odd-mass ones, and there are suggestions of effects due to unclosed proton shells on more chaotic dynamics.
