The need to determine constituent elements in materials so as to meet various technological demands in many fields is of an extreme importance. This work is an attempt to establish the efficacy of using non-destructive neutron activation methods based on instrumental gamma-ray spectrometry for...

This dissertation considers the single quantum pair annihilation of positrons with bound K-shell electrons in heavy atoms. It gives numerical calculations of the total cross section. By means of the method due to Basbas et a/.14, the binding-energy effect and its contribution to SQA cross...
