Discrete Convolution-Based Energy Spectrum Configuring Method for the Analysis of the Intrinsic Radiation of <sup>176</sup>Lu

There has been considerable interest in inorganic scintillators based on lutetium due to their favorable physical properties. Despite their advantages, lutetium-based scintillators could face issues because of the natural occurring radioisotope of <sup>176</sup>Lu that is contained in na...
