Identification of the Lowest T=2, J^{π=}0^+ Isobaric Analog State in ^{52}Co and Its Impact on the Understanding of β-Decay Properties of ^{52}Ni

Masses of ^{52g,52m}Co were measured for the first time with an accuracy of \sim 10 keV, an unprecedented precision reached for short-lived nuclei in the isochronous mass spectrometry. Combining our results with the previous \beta-\gamma measurements of ^{52}Ni, the T=2, J^{\pi}=0^+ isobaric analog state (IAS) in ^{52}Co was newly assigned,... Show more
