Determination of 51Cr and 241Am X-ray and gamma-ray emission probabilities per decay

In this paper results of X-ray and gamma-ray emission probabilities per decay of 51Cr and 241Am are presented. The measurements were carried out by means of HPGe planar and REGe spectrometers. The activity of 51Cr and 241Am samples was determined in a 4πβ−γ coincidence counting system. The HPGe spectrometers were calibrated in a well defined geometry by means of 54Mn, 55Fe, 57Co, 133Ba, 152Eu, 166mHo and 241Am sources, previously standardized in a 4πβ−γ coincidence system. The MCNP Monte Carlo code was used for simulation of the REGe spectrometer calibration curve, for the selected geometry, and compared with the experimental curve. The experimental results were compared with data from literature.
