C165500200008 SAMPLE Be3N2 targets, nitrogen gas targets, and a thin C165500200009 target formed by proton bombardment of a copper foil C165500200010 in a nitrogen atmosphere. C165500200011 METHOD (ACTIV) After bombarding for several days, two-minute C165500200012 activity was observed to come from the spot on the C165500200013 copper foil which had been hit by the proton beam in C165500200014 a nitrogen atmosphere. Hence to obtain cross-section C165500200015 values it was necessary to obtain plots of yield C165500200016 against target pressure. C165500200017 ERR-ANALYS (DATA-ERR) Incomplete description of uncertainties. C165500200018 (ERR-1) The overall determination of counting C165500200019 efficiency is believed to be accurate to 10 percent.
