Cross correlation of low-lying levels of even-even nuclei
M. H. Simbel, A. Y. Abul-Magd
We consider the cross correlations of low-lying energy levels of nuclei belonging to small intervals of the excitation-energy ratio R_{4/2} of the first 4^+ to 2^+ states. The mean…
Phenomenological model for symmetry breaking in chaotic system
A. Y. Abul-Magd, M. H. Simbel
We assume that the energy spectrum of a chaotic system undergoing symmetry breaking transitions can be represented as a superposition of independent level sequences, one increasing…
Regularity and Chaos in low-lying 2+ states of even-even nuclei
A. Y. Abul--Magd, H. L. Harney, M. H. Simbel +1
Using all the available empirical information, we analyse the spacing distributions of low-lying 2+ levels in even-even nuclei by comparing them with a theoretical distribution cha…
Statistical Analysis of Composite Spectra
A. Y. Abul-Magd, H. L. Harney, M. H. Simbel +1
We consider nearest neighbor spacing distributions of composite ensembles of levels. These are obtained by combining independently unfolded sequences of levels containing only few…
Statistics of 2+ Levels in Even-Even Nuclei
A. Y. Abul-Magd, H. L. Harney, M. H. Simbel +1
Using all the available empirical information, we analyze the spacing distributions of low-lying 2-plus levels of even-even nuclei. To obtain statistically relevant samples, the nu…
Influence of symmetry breaking on the fluctuation properties of spectra
A. Abd El-Hady, A. Y. Abul-Magd, M. H. Simbel
We study the effect of gradual symmetry breaking in a non-integrable system on the level fluctuation statistics. We consider the case when the symmetry is represented by a quantum…
