Power spectrum of nuclear spectra with missing levels and mixed symmetries

Abstract: Sequences of energy levels in nuclei are often plagued with missing levels whose number and position are unknown. It is also quite usual that all the quantum numbers of certain levels cannot be experimentally determined, and thus levels of different symmetries are mixed in the same sequence. The analysis of these imperfect spectra (from the point of view of spectral statistics) is unavoidable if one wants to extract some statistical information. The power spectrum of the δ q statistic has emerged in recent yea… Show more

“…It was demonstrated numerically in Ref. [44] that the power spectrum [45,46] is a powerful statistical measure to discriminate between deviations caused by missing levels and by the mixing of symmetries. Additional evidence for these effects may be obtained on the basis of commonly used statistical measures for short-and longrange spectral fluctuations [43].…”

“…1) we can obtain the energy time series of the fluctuations. In [10,11] the method of power spectrum analysis (PS) [14,15,16,17] is used to study the statistical of fluctuations of energy time series. Following the 1/f β noise convention, three of the most conventional noises present in nature are for β = 2, 1, 0 corresponding to thermal (Brownian), chaotic and Poisson noise respectively [12].…”
