We discuss how ultra-relativistic heavy-ions collisions may help in understanding some aspects of low energy nuclear structure. We analyze the interesting case of alpha-alpha interactions, alpha-clustering and the possible implications in the elliptic and triangular flow of 12C-208Pb collisions. http://arxiv.org/pdf/1411.5807.pdf http://dx.doi.org/10.1103/PhysRevC.90.064902 http://dx.doi.org/10.1088/1742-6596/569/1/012032 http://dx.doi.org/10.1103/PhysRevLett.112.112501 http://dx.doi.org/10.1063/1.2973487 http://arxiv.org/pdf/0709.4134.pdf
