Nearest Neighbour Level Spacing and Level Curvature Distributions of Single-Particle in Heavy Nuclei

  • The underlying Hamiltonian involved with the rotating two-center shell model is multi-parameter dependent and belongs to the Gaussian unitry ensemble(GUE).It is found that the spacing distribution and two curvature distributions(with respect to the separation and the cranked frequency,respectively)of the levels individually approach to those of GUE in the different regions of separation and cranked frequency.They,however,share a common parameter region.It is suggested that the chaotic motion of the single-particle in a heavy nucleus is possibly realized in the condition of superdeformation and high spin.

Abstract: The underlying Hamiltonian involved with the rotating two-center shell model is multi-parameter dependent and belongs to the Gaussian unitry ensemble(GUE).It is found that the spacing distribution and two curvature distributions(with respect to the separation and the cranked frequency,respectively)of the levels individually approach to those of GUE in the different regions of separation and cranked frequency.They,however,share a common parameter region.It is suggested that the chaotic motion of the single-particle in a heavy nucleus is possibly realized in the condition of superdeformation and high spin.
