SAMPLE     A multilayered C/LIF/Au sample was used for the cross  
           section measurements. A thin lif film (about 50        
           mug/cm2) was evaporated on a self-supporting C target  
            (about 30 mug/cm2) and further coated with a thin Au  
           layer (about 20 mug/cm2) for beam dose normalization;  
           the gold layer could also prevent lithium fluoride from
           being oxidised.

           (EXTB) During the measurements proton beam currents    
           were in the range 10-40-Na, depending on beam energy,  
           in order to keep the count rate low enough to have     
           negligible pile-up effects (<0.5%).  Each measurement  
           was allowed to continue until obtaining at least 2000  
           counts in all the elastic scattering peaks.
