FACILITY   (VDG,2GERKFK) The Karlsruhe 3.7-MV Van de Graaff       
            accelerator operated n DC mode with current of about  
            100 microA (for Li targets) or up to 150 microA for   
            LiF targets.                                          
INC-SOURCE (P-LI7) Neutrons were produced via the Li-7(P,N)Be-7   
            source by bombarding a 30-mum thick layers of metallic
            Li or crystalline LiF on a water-cooled Cu-backings   
            with protons of 1912 keV. Neutrons were emitted into  
            forward cone of 120 deg opening angle.                
METHOD     (ACTIV) Several independent activations were carried   
            out for each isotope with modified exp. parameters.   
           (STTA) Samples were irradiated in close contact with   
            the Li target.

DETECTOR   (GLASD) At irradiation the neutron flux was recorded   
           in intervals of 60 or 90sec using a Li-6 glass detector
           91 cm downstream of Li target.                         
ADD-RES     Using the energy dependencies of normalized evaluated 
           cross sections MACS were extrapolated in energy range  
           kT=160-260 keV. Given in Table XVI.

           Energy and efficiency calibrations have been carried   
           out with a set of reference gamma sources in the energy
           range between 60 and 2000 keV.                         
CORRECTION For self-absorption.                                   
ANALYSIS   The two strongest transitions, 124 keV and 496 keV     
           were not used in this analysis because these lines are 
           affected by coincidence summing effects (summing-out   
           into the 620keV transition).Owing to the short isomeric
           half-life 14.6 min the partial cross section to isomer 
           could not be determined.
