Statistical analysis of the Doppler broadening coincidence spectrum of electron-positron annihilation radiation in silicon
(ELSEVIER SCIENCE BV, 2009)
We report a statistical analysis of Doppler broadening coincidence data of electron-positron annihilation radiation in silicon using a (22)Na source. The Doppler broadening coincidence spectrum was fit using a model function ...
Positron annihilation spectroscopy techniques applied to the study of an HPGe detector.
(São Sebastião, 2012-09-02)
Doppler Broadening Spectroscopy of the large Ge crystal of an HPGe detector was
perforrned using positrons from pair production of 6.13 MeV ϒ-rays from the 19F(p,αϒ) 16O reaction. Two HPGe detectors facing opposite sides ...
