Abstract
The result of an experimental evaluation of the K-shell fluorescence yield, omega K, of monocrystalline Ge is reported. The procedure makes use of the information contained in the escape peaks which are present in the characteristic X-ray spectra given by an HP Ge detector. Details of the experimental methodology, peak area evaluations and uncertainty treatments are described. A value omega K=0.549+or-0.011 is obtained and compared with recent values obtained from experiment, theory, interpolation or normalisation. The authors consider the effects of the outer-shell configuration and the use of theoretical photoelectric cross section values.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
