Calculation of Coulomb breakup cross sections using a new Coulomb dynamical polarization potential

A new method for calculating the Coulomb breakup of unstable neutron-rich isotopes at high energies is presented. The calculations employ eikonal approximation and use a dynamical polarization potential, calculated by solving Schr\"odinger equation entire motion exotic projectile as two-body cluster structure using adiabatic incorporating excitations to continuum. Calculations some are compared with dissociation cross section data found be in good agreement.
