Masses of short-lived ${}^{49}Sc$, ${}^{50}Sc$, ${}^{70}As$, ${}^{73}Br$ and stable ${}^{196}Hg$ nuclides

Abstract

Mass measurements of ${}^{49,50}$Sc, ${}^{70}$As, ${}^{73}$Br and ${}^{196}$Hg nuclides produced at CERN's radioactive-ion beam facility ISOLDE are presented. The measurements were performed at the ISOLTRAP mass spectrometer by use of the multi-reflection time-of-flight and the Penning-trap mass spectrometry techniques. The new results agree well with previously known literature values. The mass accuracy for all cases has been improved.
