TITLE      On the photon self-absorption correction for thin-     
           target-yields vs. thick-target-yields in radionuclide  
           production.

SAMPLE     Thick targets W-natural isotopic composition and       
           several 500 mg of highly enriched 99.9% W-186 powder   
           and W-180 0.001%, W-182 0.01%, W-183W 0.005%, W-184    
            0.09% were used.                                      
           The powdered targets were pressed up to 15M Pabyan     
           hydraulic crystallography press in between two         
           accurately measured high purity Al foils, 10 mm of     
           nominal diameter, 120 and 200 mm thick. During the     
           irradiation,the Al-W-186-Al stacks were enveloped      
           in between other two further calibrated high purity    
           12 mm  Al foils, 99.999%, 20*20 mm**2 area in order to 
           prevent any losses and contaminations of activated     
           W-186 powder during and /or after their radiation, i.e.
           these sheets ware taken away after their radiation.    
           The Al foils thickness was chosen in order to obtain   
           values of the energies incident on the enriched W-186  
           targets comparable for protons  (13.6+-0.2 MeV) and    
           deuterons(13.4+-0.2 MeV) beams.
