Higher-order dynamical effects in Coulomb dissociation

We study the effect of higher-order processes in Coulomb dissociation of 11Li by numerically solving the three-dimensional time-dependent Schrödinger equation for the relative motion of a di-neutron and the 9Li core. Comparisons are made to first-order perturbation theory and to measurements. The calculated Coulomb reacceleration effects improve the agreement with experiment, but some discrepancy remains. The effects are smaller in the dissociation of 11Be, and they decrease with increasing beam energy.

Signature for the existence of eta-mesic nucleus.

It is shown that strongly-bound \ensuremath{\eta}-nucleus systems, which we term \ensuremath{\eta}-mesic nuclei, can be formed between an \ensuremath{\eta} meson and nuclei of mass number Ag10. We show that a distinct experimental signature for the formation of the \ensuremath{\eta}-mesic nucleus can be observed in (${\ensuremath{\pi}}^{+}$,p) reactions. The formation cross sections are predicted. Effects of higher order dynamics on the predicted width of the \ensuremath{\eta}-mesic nucleus are also estimated.
