Trace elements determination in high purity germanium and lithium

  • 1. Pakistan Inst. of Nuclear Science and Technology, Islamabad (Pakistan). Nuclear Physics Div.

Description

Neutron activation analysis was employed to the determination of 29 trace impurities in high-purity Al foils and semiconductor grade Ge. In order to determine very low contents of U and /sup 239/Th and /sup 233/Pa as activation products were separated by using anion exchange and LaF/sub 3/ coprecipitation method. The impurity contents found to be low in high-purity Al and even lower in semiconductor grade Ge. Therefore adverse effects would be negligible. Our data could partially be compared with the data reported in literature and found in good agreement. (author) 5 tabs; 10 refs
