Very precise elastic cross sections have been measured in a very forward angular range (up to 1.6 laboratory) for the ' C+ ' C system at six energies not too far above the Coulomb barrier. From these data the symmetrized nuclear scattering amplitude f~(0) for small angles and the total reaction cross section 0. + could be derived making use of the generalized optical theorem for charged particles. It was found that~f~(0)~exceeds zero significantly in all cases investigated. This means that a forward nuclear glory exists in the ' C+' C scattering. This is the first time that evidence for a forward nuclear glory is deduced from experimental data.

The yield for molecular ions desorbed from a valine sample has been measured as a function o f the charge state of the incident fast heavy ions. The data can be interpreted in the following way: (i) the yield depends on the square of the primary ion charge, and (ii) desorption takes place not only at the sample surface but also within a layer 'underneath. The depth of this layer is smaller than the depth needed to achieve charge state equilibrium for the primary ions.
