title: Activity measurement of a 176Lu sample using coincidence peaks and Monte Carlo simulations.
abstract: We present the results of the activity measurement of a sample of the rare isotope 176Lu, obtained by gamma-ray spectrometry through the use of 22 peaks in an energy spectrum acquired with a 300 cc well-type HPGe detector located in the Modane underground facility below the French Alps. Of the above peaks, 17 are coincidence peaks between two or three gamma-rays or X-rays. True coincidence summing corrections were made using our Coincal code. Monte Carlo simulations were carried out for calibration purposes.
