Abstract
The first results on statistical properties of quantum quasidegeneracy are presented. A physical interpretation of the Shnirelman theorem which predicted bulk quasidegeneracy is given. Conditions for the strong impact of degeneracy on quantum level statistics are formulated, which allow us to extend the application of the Shnirelman theorem to a broad class of quantum systems.Keywords
