摘要
The spectral statistics of calcium isotopes are studied with realistic shell-model calculations, For these nuclei, there are significant deviations from the predictions of the random-matrix theory. In particular, we observe an order-chaos transition when the excitation energy is increased and a clear quantum signature of the breaking of integrability when the single-particle energy spacings are decreased.
