SAMPLE     A gas target cell filled with 1 mbar nitrogen gas of   
           natural isotopic composition 0.366% N-15, was used.    
           During the experiment, nitrogen gas of natural isotopic
           composition and 99.9995% chemical purity was flowing   
           through the windowless target cell with a flux of      
            2 l/s. No recirculation was used, so the gas was      
           discarded after one passage through the target.

REACTION   (7-N-15(P,G)8-O-16,,SIG,,SFC)                          
COMMENT    *By authorsr*.En-cm is effective center-of-mass        
           interaction energy.                                    
           *By authors*.The present data are more precise than    
           previous direct experiments(see Rel-Ref-Hebbard,1960   
           and C.Rolfs et.al,1974) and are about a factor 2 lower 
           than the values adopted in reaction rate compilations  
            (see Rel-Ref-G.Caughlan et.al,1988 and                
           C.Angulo et.al,1999)
