Optimized data evaluation for k(0)-based NAA

k(o)-NAA allows the simultaneous analysis of up-to 67 elements. The k(o) me thod is based on calculations using a special library instead of measuring standards. For an efficient use of the method, the calculations and resulti ng raw data require optimized evaluation procedures. In this paper two effi cient procedures for nuclide identification and gamma interference correcti on are outlined. For a fast computation of the source-detector efficiency a nd coincidence correction factors the matrix interpolation technique is int roduced.
