A ug 1 99 8 Nonlinear Enhancement of the Multiphonon Coulomb Excitation in Relativistic Heavy Ion

چکیده
We propose a soluble model to incorporate the nonlinear effects in the transition probabilities of the multiphonon Giant Dipole Resonances based on the SU(1,1) algebra. Analytical expressions for the multi-phonon transition probabilities are derived. Enhancement of the Double Giant Resonance exci-tation probabilities in relativistic ion collisions scales as (2k + 1)(2k) −1 for the degree of nonlinearity (2k) −1 and is able to reach values 1.5 − 2 compatible with experimental data. The enhancement factor is found to decrease with increasing bombarding energy.

We construct a three-dimensional analytically soluble model of the nonlinear effects in Coulomb excitation of multiphonon Giant Dipole Resonances (GDR) based on the SU(2,1) algebra. The full 3-dimensional model predicts further enhancement of the Double GDR (DGDR) cross sections at high bombarding energies. Enhancement factors for DGDR measured in thirteen different processes with various proje...

We study the effects of channel coupling in the excitation dynamics of giant resonances in relativistic heavy ions collisions. For this purpose, we use a semiclassical approximation to the Coupled-Channels problem and separate the Coulomb and the nuclear parts of the coupling into their main multipole components. In order to assess the importance of multi-step processes, we neglect the resonanc...
