  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.
