L alpha, L beta(1) and L gamma emission line shapes and intensity ratio values have been measured for the elements Nd, Sm, Gd and Tb and for a large number of their compounds. The measurements were done using the EDXRF system, where special attention was given to minimizing the errors in various corrections such as self absorption and detector efficiency. All the lines were excited using a 100 mCi Am-241 annular radioactive source. The energy shifts and L alpha/L beta(1) and L alpha/L gamma intensity ratio values of X-rays were examined for chemical effect. The measured L alpha/L beta(1) and L alpha/L gamma intensity ratios were compared with the experimental and theoretical data in literature. (C) 2016 Elsevier B.V. All rights reserved.
