Nuclear transients

Nuclear scattering is classically analysed using realistic conservative interactions. Due to chaoticity of motion, the projectile can stay in the vicinity of the target for a long time. Such phenomena are called transients. We investigate properties of transients: fractal dimensions, Lyapunov exponents and mean lifetimes. We conclude that the lifetime of transients is similar to that of single-particle resonances. It rises substantially when we consider a more general system, with larger number of degrees of freedom.
