In this paper we outline the concept and characteristics of quantum chaos in two different approaches, the random matrix theory fluctuations and the time series fluctuations. Then we discuss the theoretical and experimental evidence of chaos in nuclei. Theoretical calculations, especially shell-model calculations, have shown a strongly chaotic behavior of bound states in regions of high level density. The analysis of experimental data has shown a strongly chaotic behavior of nuclear resonances just above the one-nucleon emission threshold. For bound states, combining experimental data of a large number of nuclei, a tendency towards chaotic motion is observed in spherical nuclei, while deformed nuclei exhibit a more regular behavior associated to the collective motion. On the other hand, it had never been possible to observe chaos in the experimental bound energy levels of any single nucleus. However, the complete experimental spectrum of the first 151 states up to excitation energies of 6.20 MeV in the Pb-208 nucleus have been recently identified and the analysis of its spectral fluctuations clearly shows the existence of chaotic motion. eng Atribución 3.0 España Chaos in nuclei: Theory and experiment journal article URL https://docta.ucm.es/bitstreams/1f3eccf1-1398-46a9-ba15-2fea7b5b7902/download File MD5 a5ff66be84c00967dd840bdbd8cc6d5e 442592 application/pdf GómezG JM02libre+CC.pdf URL https://docta.ucm.es/bitstreams/8a6e0287-a30a-4a3c-956e-e2263249ff3b/download File MD5 d5fa321094bcb3111344c1317e28cd7c 25713 text/plain GómezG JM02libre+CC.pdf.txt
