Fig. 7.


Left: nearest neighbors spacing distribution , with 1344 frequency levels obtained from eight independent spectra: Ω/Ωk = 0.481 (206 odd levels), Ω/Ωk = 0.545 (223 odd levels, 105 even levels), Ω/Ωk = 0.589 (217 odd levels, 96 even levels), Ω/Ωk = 0.658 (207 odd levels, 120 even levels) and Ω/Ωk = 0.809 (170 odd levels). Right: integrated distribution N(s) for all eight independent spectra. In both panels the dashed line the Wigner surmise and the dotted line is the prediction for Poissonian spectra.
