19F (p, alpha gamma) 16O reaction: HPGe detector response function and gamma-ray relative yields

Abstract

The 6.1, 6.9 and 7.1 MeV photon yields in the reaction with protons in the 1.32 to 1.42 MeV energy range were determined from the comparison between experimental and simulated spectrum. The gamma-ray spectra were measured with a HPGe detector which was 72.5 mm in diameter and 60.5 mm in length. The reaction kinematics and the detector response function were simulated by different programs using the Monte Carlo method. The relative photon yields were obtained from the least-squares fit of the experimental gamma-ray spectra to the convolution of the detector response function with the photon energy distribution arising from the reaction kinematics.
