Giant Resonances in Coulomb Excitations of Relativistic Ions
M. S. Hussein, A. F. R. de Toledo Piza, O. K. Vorov
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…

Distribution of matrix elements of random operators
M. S. Hussein, M. P. Pato
It is shown that an operator can be defined in the abstract space of random matrices ensembles whose matrix elements statistical distribution simulates the behavior of the distribu…

On the Evidence for Postacceleration Effects in Breakup Reactions with Halo Nuclei
C. A. Bertulani, M. S. Hussein, M. P. Pato +1
We study the postacceleration of charged fragments in reactions with unstable nuclear beams. For elastic breakup processes we show that the postaceleration effect can be well under…
