A water sample containing 10**(-12) g C039500100014 enriched 10B and 1.3 x 10**(-12) g enriched 6Li C039500100015 Two targets irradiated at 135 MeV. C039500100016 METHOD (ASEP,BCINT) The cross sections were normalized to C039500100017 a radiochemically determined Be-7 absolute value.

C039500200007 Hence, the contribution of 7Be to the peak at mass 7 isC039500200008 only about 1% of the contribution of 7Li, and we have C039500200009 taken the ratio 7Li/6Li to be that of the ion currents C039500200010 at these two mass values except for this small C039500200011 correction of the mass-7 peak which we base on the C039500200012 height of the mass-8 peak.
