Abstract
The behaviour of the low-lying quasiparticle energy levels in a superconductor-normal metal-superconductor structure is investigated analytically and numerically. The energy levels are periodic in the order parameter phase difference between the superconducting regions with a period of 2 pi . The statistical properties of the spectra exhibit a transition from GOE to GUE statistics as a function of the phase difference with a period of pi .Keywords
