... predicts gamma spectrum for each measurement. The predicted spectra agreed partially with measured spectra. This software has a XML database which includes nuclear data for frequently used materials in NAA. Neutron Neutron cross section data from ‘‘ Tables for Neutron Activation Analysis’’ , photon cross section data from Berger and Hubbell’s XCOM photon cross sections database [ 2], and isotope decay from from Lund/LBNL database are included in this
database.
