    "abstract": "In order to understand the origin of one-body dissipation in nuclei, we\nanalyze the behavior of a gas of classical particles moving in a\ntwo-dimensional cavity with nuclear dimensions. This \"nuclear\" billiard has\nmultipole-deformed walls which undergo periodic shape oscillations. We\ndemonstrate that a single particle Hamiltonian containing coupling terms\nbetween the particles\u0027 motion and the collective coordinate induces a chaotic\ndynamics for any multipolarity, independently on the geometry of the billiard.\nIf the coupling terms are switched off the \"wall formula\" predictions are\nrecovered. We discuss the dissipative behavior of the wall motion and its\nrelation with the order-to-chaos transition in the dynamics of the microscopic\ndegrees of freedom.",
