  112   Sun May 9 20:34:47 2021 Rui-Jiu ChenAnalysisComparison of frequency spectrum between 72Ge and other isotopeThis some preliminary analysis results by
using  NTCAP data.   The IQ rate of NTCAP
is 20 MSamples/seconds. I analyzed data files

see what might be the isomer.

  127   Mon May 10 04:08:13 2021 Iris (Chris C., Jeff C.)AnalysisComparison between 72Ge: 10th 1-2am on 245 MHz> Following Xiangcheng Chen's analysis, I
analysed 11 ms time slices separated by 25
ms to see the evolution of the potential
