``Chaos" in Nuclear High Spin Spectroscopy
Yang Sun, Da Hsuan Feng, Hsi-Tseng Chen, Hua Wu
Abstract
The Projected Shell Model with zero-, two- and four-quasiparticle configurations is used to investigate the level statistics, i.e. chaoticity, of high spin spectroscopy. The model can describe many high spin phenomena and with the present configuration space has sufficient number of levels for statistical analysis. It is found that the degree of chaoticity has a sensitive dependence on the classification of levels in question, and that it steadily increases with excitation energy and angular momentum.
