The mass of $^{32}Ar$ and $^{33}Ar$ for fundamental tests
Masses of the short-lived radionuclides ^32Ar (T_1/2=98 ms) and ^33Ar (T_1/2=173 ms) have been determined with the Penning trap mass spectrometer ISOLTRAP. Relative uncertainties of 6.0 x 10_-8 (deltam=1.8 keV) and 1.4 x 10_-8 (deltam=0.44 keV), respectively, have been achieved. At present, these ne...

| description | Masses of the short-lived radionuclides ^32Ar (T_1/2=98 ms) and ^33Ar (T_1/2=173 ms) have been determined with the Penning trap mass spectrometer ISOLTRAP. Relative uncertainties of 6.0 x 10_-8 (deltam=1.8 keV) and 1.4 x 10_-8 (deltam=0.44 keV), respectively, have been achieved. At present, these new mass data serve as the most stringent test of the quadratic form of the isobaric-multiplet mass equation IMME. Furthermore, the improved accuracy for the mass of ^32Ar yields a better constraint on scalar contributions to the weak interaction. New mass values have also been measured for ^44Ar and ^45Ar, and a 20sigma deviation for ^44Ar from the literature value was found and interpreted. |
