    Relativistic effects in heavy-ion Coulomb scattering

    Ravinder Kumar🇺🇸 · C.A. Bertulani🇺🇸 · G. Robinson🇺🇸

    The role of relativistic corrections in Coulomb scattering of heavy ions at intermediate energy collisions ( MeV/n) is investigated by numerically solving a full set of coupled equations. We compare two methods, (a) one involving an exact account of interaction retardation with (b) a method based on the expansion of effective Lagrangians in powers of the ion velocities, .Our study makes it possible to infer the relevance of kinematic corrections, retardation, and magnetic interactions such as the Darwin force. We show that analytical formulas are able to describe all aspects of experimental interest in relativistic effects in heavy-ion Coulomb scattering at intermediate energies without having to solve numerically the coupled equations.

    Superfluid effects in collision between systems with small particle number

    Guillaume Scamps · Yukio Hashimoto

    The interpretation of the new effect of the superfluidity in reactions with small number of particles is discussed in a simple model where the exact solution is accessible. It is find that the fluctuations of observable with the gauge angle reproduce well the exact fluctuations. Then a method of projection is proposed and tested to determine the transfer probabilities between two superfluid systems.
