Possible manifestations of the chaotic phenomena in the nuclear physics applications

This aspect will be treated by applying the Hamilton equations of motion to the point particles modeling the nucleons with spin, moving in the deformed Woods-Saxon potential. We intend to investigate the role of the diffusivity of the nuclear potential as a chaos-generating factor, together with the spin-orbit interaction and the effect of the exotic deformations such as exotic octupole deformations of various symmetries, and super- and hyper-deformations. We will calculate the Lyapunov exponents and perform the analysis of the time-averages of physical observables in order to investigate the effect of symmetries on the "stronger or weaker" manifestations of classical chaos on particles moving in the nuclear-type realistic potentials.

Within the similar approach we are going to introduce a model of a two-body residual interaction (of the pairing type) and compare the effect of such an interaction with the realistic interaction strength on the chaotic properties of the classical trajectories. In such a way the relative importance of the typical "chaos generating nuclear mechanisms" such as: diffusivity and deformation of the central nuclear potential, varying intensity of the nuclear spin-orbit effect and the two-body pairing forces will be estimated.

$\rightarrow$ The above purely classical tests will be compared to the analogous tests obtained with the help of the Schrödinger equation with the hamiltonian of exactly the same properties (form of the potential, types of deformations, symmetries, spin-orbit strengths).
