    "abstract": "Nonlinear excitations of nuclear density are considered in the framework of\nsemiclassical nonlinear nuclear hydrodynamics. Possible types of stationary\nnonlinear waves in nuclear media are analysed using Nonlinear Schroedinger\nequation of fifth order and classified using a simple mechanical picture. It is\nshown that a rich spectrum of nonlinear oscillations in one-dimensional nuclear\nmedium exist.",
