INC-SPECT  Metallic absorbers of Ta, Ni, and stainless steel used C049900100008 
            at entrance window of cell to degrade initial proton  C049900100009 
            energy of 26 MeV.  Energy controlled by adjusting     C049900100010 
            thickness of absorbers.                               C049900100011

METHOD     (ACTIV) All 22Na produced was bound to Monel liner in  C049900100015 
            cell. Liner was removed from cell after activation    C049900100016
