CORRECTION To estimate the heavy element impurities, identical    3051900100023 
           targets were irradiated in the thermal column of the   3051900100024

           detector. they were found to be = 1.3ppm approx.       3051900100026 
           appropriate corrections were applied in determining    3051900100027
