Knowing their thickness and masses the 2309200600007 intensities of the prompt gamma rays in the Ge isotopes2309200600008 could be related to the reference transition in gold at2309200600009 247 keV, relying on a cross section of 5.56(8) b from 2309200600010 STI/PUB/1263(http://www-nds.iaea.org/pgaa/tecdoc.pdf). 2309200600011 Alternatively, the partial cross-sections were derived 2309200600012 from the decay peaks of 77Ge observed in the prompt 2309200600013 spectrum. Both approaches are in good agreement, i.e. 2309200600014 within 0.15% and 1.8% depending on the line used for 2309200600015 normalization. 2309200600016 Applying the obtained renormalization factor of 2309200600017 fr = 0.395(15) to the relative intensities given in 2309200600018 table A.1 (=Subent 005) the partial cross-sections can 2309200600019 be calculated.
