by WebElements: the periodic table on the web

A physicsweb.org article1 states that an international team working at the ISOLTRAP mass spectrometer at CERN has determined the masses of two isotopes of argon (32Ar and 33Ar) with the highest precision ever. This is important if you want “to place constraints on aspects of the weak interaction that are not included in the Standard Model”.

Abstract:1 masses of the short-lived radionuclides 32Ar (T1/2=98   ms) and 33Ar (T1/2=173   ms) have been determined with the Penning trap mass spectrometer ISOLTRAP.
