  58   Wed Apr 2 00:08:57 2025 Ruijiu Chen,ShahabAnalysisthe peak corresponding to 194Pb⁸²⁺ was mixed with signals from some unknown ions.I examined the spectrum of 194Pb at the 211
harmonic. It was observed that the peak corresponding
to 194Pb82+ was mixed with signals

in our data analysis. However, 63% of the
injections have a height below 100, and these
