N2 - A procedure is reported for the determination of Ni, Ge, Ru, Au, Ir, Zn, Ga, Cd, In and U in meteorites and lunar materials. The precision in multiple determinations at the 95% confidence level is less than 10% except for gold (15%). Ruthenium and uranium are determined by counting 97Ru and 103Ru x-rays; the chemical yield is determined from 106Ru added before sample dissolution. The activity of 116mIn is determined with improved sensitivity from integral counts in the region 1.5-3.0 MeV on a NaI(TI) detector.
